Fortress UPS Protocol

The table on the next few pages shows the parameters that you can view or program from a terminal or computer. Some of these parameters keep track of information (like Time or Date) or display operating and power conditions (like voltage, current, or temperature). Other parameters, (Like User ID) let you program the Fortress for special operating conditions.

When you use the Fortress commands to display and program parameters, you can identify the parameter with either its number or name. If you use the name, you can enter the whole parameter name or just the letters in the short form. (See the Name column in the parameter table).

Passwords restrict access to some parameters; see the "Password to Change" column in the table and Section 40 1.

502 Automatic Startup and Shutdown (Parameters 90-93)

If you do not want the Fortress to run constantly, you can program it to startup and shut down automatically using parameters 0, II, and 90-93. Just follow the steps below.

1. You must enter the Service password before you can change parameters 90-93. To enter the password, use the command pw 2639.

2. Using the display command, display parameters 0 and 11 to make sure the time and the day of the week are correct. (Note that parameter 0 shows the time in 24-hour or military time.) If both parameters are correct, go to step 2. If not, follow steps a-b:

a. Use this command to change the time: program time <new time>. Be sure to use the 24-hour system. For example, if the time is 9:30 a.m., use the command program time 09:30. If the time is 7:00 p.m., use the command program time 19:00.

b. To change the day of the week, use this command: program day <new day of week>. For the new day of the week, 0 = Sunday, I = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, and 6 = Saturday. For example, if the day of the week is Monday, use the command program day 1.

3. Parameters 90-93 let you set up automatic startup and shutdown.

4. Parameter 91 (ontiniedays or ontd) lets you choose which days you want the Fortress to automatically shut down. When you receive the Fortress, this is set to 0, which means none of the days have been selected.

If you want the Fortress to start automatically every day, use this command: program ontd 127. If you only want Fortress to operate some days, use the table below. In the right column enter "0" for each day you do not want the Fortress to operate. For the days you do want the Fortress to operate, enter the day's value from the second column. Then, add the right column and use this command to change the parameter setting: program ontd <total of right column>.




Example: If you wanted the Fortress to operate automatically Monday through Friday, you would write "0" next to Sunday and Saturday and the values next to the other day. 0 + 2 + 4 + 8 + 16 + 32 + 0 = 62, so you would use the command program ontd 62.

5. Parameter 90 (powerontime or ont) sets the time you want the Fortress to start automatically. When you receive the Fortress, this parameter is set to 8:00 a.m. If you want the Fortress to start at a different time, use this command: program ont <new start time>. Be sure to use 24-hour or military time. For example, if you want the Fortress to start at 9:00 a.m., use the command program ont 09:00. If you want the Fortress to start at 3:00 p.m., use the command program ont 15:00.

6. Parameter 92 (powerofftime or offt) sets the time you want the Fortress to shut down automatically. When you receive the Fortress, this parameter is set to 17: 00, which is 5: 00 p.m. If you want the Fortress to shut down at a different time, use this command: program offt <new shutdown time>. Be sure to use 24-hour or military time.

7. Parameter 93 (offtimedays or oftd) lets you choose which days you want the Fortress to shut down. When you receive the Fortress, this is set to 0, which means none of the days have been selected. If you want the Fortress to shut down automatically every day, use this command: program oftd 255.

If you only want Fortress to shut down some days, use the table on page 29 to calculate the setting just as you did for parameter 9 1. If you want the Fortress to start and shut down on the same days, you can use the setting you calculatedfor parameter 91.

8. Clear the Service password using the clearpassword command.

503 Choosing Which Alarms Enable the Alarm Contact (Parameter 81)

When you receive the Fortress, the alann contact (pin 5) only closes for the Low Battery, Near Low Battery, and Low Runtime alarms. This setting is important ifyou are using yourfree CheckUPS II Suite software pack-age or other automatic shutdown software. However, if you are not using CheckUPS and you would like other alarms to close the contact, you can use parameter 81 to determine which alarms will close the contact. (See Section 504 for information about other settings that affect the alarm contact.)

No matter how you program parameter 81,when the UPS is off, the alarm contact will be open.

To program parameter 8 1, follow these steps:

1. Enter the Service password using the command password 2639.

2. Display parameter 81 using the display 81 command.

3. The table on the next page will help you calculate the new parameter settmig based on the alarms that you want to activate the contact. If you do not want any of the alarms to activate the contact, write "0" for the total. If you want some of the alarms to activate the contact, see the table to find the Alarm Value for each of these alarms; write the value for these alarms in the third column of the table. Write "0" for alarms that should not activate the contacts. Then, add the numbers in the third column. For example, to enable alarms A (Low Battery), B (Near Low Battery), and C (High Battery),write "I" for alarm A, "2" for alarm B, "4" for alarm C, and "0" for the rest of the alarms. Ile total is 7.

If you are using the Fortress with an AS/400, you should ONLY enable the alarm contact for the Low Battery, Near Low Battery, and Low Runtime alarms. In the blanks, A = 1, B = 2, D=8, and C and E- K = 0. The total = 11.

4. Now, change the parameter 81 setting to the total you found in step 3. To do this, use the program 81 <new setting> command.

Example: If you would like to activate the contact for alarms A, B, and C and your total in step 3 was 7, enter the command program 81 7.

5. Use the display 81 command to display the parameter once more and confirm that you have entered the correct setting.

6. Clear the Service password using the clearpassword or cp command.

504 Changing the Settings for Alarm and Battery Contacts
(Parameters 80 and 88-89)

Parameters 80 and 88-89 let you program how the alarm and battery contacts operate.

Alarm Contact (Pin 5)

When you receive the Fortress, a Low Battery Alarm will cause the normally open contact on pin 5 to close to common (pin 4). (Section 503 tells you how to activate the contact for other alarms.) The contact is normally open because parameter 80 is set to 0)Neg when you receive the Fortress. If you would like the contact to be normally closed and to open during the alarm, you must change parameter 80 to 1)Pos. No matter how you program parameter 80, when the UPS is off, the alarm contact will be open. To change the parameter, follow these steps:

1. Enter the Service password using the command password 2639.

2. Program parameter 80 to 1)Pos using this command: program 81 1.

3. Clear the password using the clearpassword or cp command.

On Battery Contact (Pin 3)

When you receive the Fortress, the on battery contact (pin 3) is a normally open contact that closes 15 seconds after the Fortress starts running on battery power. Using parameter 88, you can change the contact to a normally closed contact. Using parameter 89, you can adjust the 15-second delay.

Parameter 88 is set to 0)Neg when you receive the UPS. This means that the contact is normally open and that it closes when the Fortress runs on battery power. To change the contact to a normally closed contact that opens when the Fortress runs on battery, follow these steps:

1. Enter the Service password using the command password 2639.

2. Program parameter 88 to 1)Pos using this command: program 88 1. No matter how you program parameter 88, when the UPS is off,the inverter contact will be open.

3. Clear the password using the clearpassword or cp command.

After the Fortress begins running on battery power, parameter 89 determines how long the Fortress will wait before closing the on battery contact. When you receive the Fortress, this parameter is set to 15 seconds. You can decrease the delay to as little as 0.1 seconds or increase it to as much as 25.5 seconds. To do this, follow these steps:

1. Enter the Service password using the command password 2639.

2. To change the delay, enter the command program 89 <new delay in seconds>. For example, if you want the delay to be 20 seconds instead of 15 seconds, enter program 89 20.

3. Clear the password using the command clearpassword or cp.

505 Changing Remote Shutdown Settings (Parameters 82-84 and 85-87)

Pin 7 Shutdown

The Remote Shutdown available on pin 7 lets you shut down the Fortress' output power through a remote switch. The switch must have a set of contacts that can short pin 7 on the UPS communication port to pin 4 (common). (Use a shielded, single twisted pair cable to connect your switch to these pins.) The connection will shut down the UPS' output power to the protected equipment. When this happens, the UPS will sound alarm "Sd" for "shutdown" (Morse code alarm H). When you are ready to restart the UPS, the shutdown switch must remove the connection to pin 7 on the UPS communication port. Then, you can press the ( | ) button to restart the UPS.

You can change the way this feature operates by using parameters 85, 86, and 87.

Parameter 85 determines whether this shutdown works with a normally open or normally closed switch. When you receive the Fortress, it is programmed to expect a normally open switch, and the Fortress shuts down when the switch input is shorted to pin 4. You can change the Fortress to work with a normally closed switch. To do this, you must change the setting of parameter 85 from 0)Neg to 1)Pos. Follow these steps:

1. Enter the Service password using the command password 2639.

2. Change the parameter setting using the command program 85 1.

3. Clear the password using the command clearpassword or cp.

Parameter 86 determines how long the shutdown signal should be. In some environments with a lot of electrical noise, the noise could mimic the shutdown signal and cause a Fortress shutdown. To avoid this problem, you can increase the amount of time that the signal must be present before Fortress recognizes it. When you receive your Fortress, this parameter is set to 0.2 seconds, By changing the parameter value, you can decrease the required signal length to 0.1 seconds or increase it to as much as 25.5 seconds. To change the value, follow these steps:

1. Enter the Service password using the command password 2639.

2. Change the parameter setting using the command program 86 <new value in seconds>. For example, if you want to change the parameter value to 2 seconds, you would use the command program 86 2.

3. Clear the password using the command clearpassword or cp.

After the Fortress recognizes a shutdown signal, parameter 87 determines how long the Fortress will wait before shutting down. When you receive your Fortress, this parameter is set to 0.1 seconds. By changing the parameter value, you can increase the delay to as much as 2000 seconds (33 minutes). Follow these steps:

1. Enter the Service password using the command password 2639.

2. Change the parameter value using the command program 87 <new delay in seconds>. For example, if you want the Fortress to delay 3 seconds, use the command program 87 3.

3. Clear the password using the command clearpassword or cp.

Pin 1 Shutdown

If your Fortress is set to Extended Signal communication mode (see Section 200), remote shutdown is also available on pin 1. If the UPS is using battery power, a +12-volt signal applied to the pin for 5 seconds will shut down the UPS 30 seconds later. The UPS willl automatically restart when the power outage ends (unless you have changed parameter 39).

You can change the way this feature operates by using parameters 82, 83, and 84.

Parameter 82 determines the type of signal on pin 1 that will start a Fortress shutdown. When you receive the Fortress, this is programmed to 0)Neg, which means ground or a -12V input causes the shutdown. If you change the parameter to 1)Pos, a +12V input shuts down the UPS. Note: +12V is available on pin 8 of the Fortress' port.
1. Enter the Service password using the command password 2639.

2. Change the parameter value using the command program 82 1.

3. Clear the password using the command clearpassword or cp.
