3) You may now select switch positions using the UP/DOWN switch. For a 2282-122-21
controller, the switch position choices are: BACKUP CH1, BACKUP CH2, or BACKUP NONE.
4) Once the Switch position is selected, push the PROGRAM/EXECUTE switch to go to the next menu.
5) Use the LEFT/RIGHT switch to move the cursor to R (return), then push the PROGRAM/EXECUTE
switch to jump to the SAVE SETTINGS menu.
1.3.3 REMOTE
To override auto switching remotely…
Note: If the unit is in Manual mode then the following remote commands will be ignored because
Manual mode overrides Remote mode.
From the serial M&C Interface:
1)
SET the unit’s switch position by sending the following command …
{aaCAx}
where: x = 0 sets the switch to BACKUP NONE
x = 1 sets the switch to BACKUP CH1
x = 2 sets the switch to BACKUP CH2
Once the switch positon is selected remotely, the unit is in Remote mode and the front panel remote
indicator will light. The unit will remain in Remote mode until one of the following occurs:
a. Switch reset command ( {CB} ) is issued.
b. The front panel Switch Reset button is pressed.
2)
From the (optional) Ethernet Interface:
Webpage:
1. Select “Backup None”, “Backup CH1”, or “Backup CH2”.
2. Click “Update Other”
SNMP:
1. Set ObjectID remoteSetPosition2282xx to 0, 1, or 2 to remotely set the switch position.
2. Set ObjectID resetSwitch2282xx to clear the Remote mode and return to Auto mode.
3. Set ObjectID switchPos to the desired position, either 1 (AMP1 to 1) or 2 (AMP2 to 1).
1.3.4 Auto Mode
Auto mode is the default mode of the controller. When in the Auto mode the controller is continuously
monitoring the status of AMP1, AMP2, and AMP3. In 1:2 configurations, if a fault is detected from AMP1 or
AMP2 then AMP3 is switched into the signal path of the faulted unit.
