Figure 17: Heavy Duty Relay Programming Grid
A minus sign (-) in a grid position indicates that the condition on that channel will not
cause this relay to activate. A plus sign (+) in a grid position indicates that the
condition on that channel will cause the relay to activate. If one or more conditions
marked with a (+) occur during normal operation, the relay will activate. Figure 17
above shows a typical relay programming grid. In the example shown, the selected
relay will activate if any or all of the following conditions occurs:
•
Channel 1 experiences a Fail condition.
•
Channel 4 experiences an Alarm 1 condition.
•
Channel 8 experiences an Alarm 2 condition.
If the relay activation settings are OK, press the UP (YES) button, then press UP
(YES) to save all the relay settings or DOWN (NO) to abort any setting changes. Skip
to step 5.
If you want to change the activation conditions, press the DOWN (NO) button and a
flashing cursor will appear in the ALARM-2/Channel 1 grid position (row 1/column 1).
•
Use the ENTER and ESCAPE buttons to move the flashing cursor to the grid posi-
tion(s) you want to change.
•
Use the UP (YES) button to insert a + in a grid position and the DOWN (NO) but-
ton to insert a - in a grid position.
•
When you are done changing the settings, press the ENTER button until the flash-
ing cursor is on the FAIL/CHannel 8 grid position, then press the ENTER button
again.
•
If the settings are OK, press UP (YES) to save them. The top display screen will
indicate that the setting are being saved.
If the settings are not OK, press DOWN (NO).
5.
The top screen prompts you to select another relay to program. To program another
relay, select the relay and repeat steps 1 through 4. If you are done programming
relays, press ESCAPE twice and then DOWN (NO) to return to normal operation.
