OPERATING RELAYS FROM THE KBD960
To operate relays from a KBD960 keyboard, you must know which GPI to call, and which auxiliary (AUX) to select on the keyboard.
You can cascade two relay units. Each relay unit has eight GPIs. Relay Unit 1 has a GPI range of 1-8, and Relay Unit 2 has a GPI range of
9-16. Refer to Tables C and D.
There are two ways you can operate relays from the KBD960.
ACTIVATING RELAYS USING F12
NOTE: You hear a brief click from the relay unit whenever you activate a momentary or latching relay contact.
Follow these steps to activate a momentary relay:
1. Go to Main Menu 1.
2. Enter a logical relay contact number (1-128).
3. Press F12.
A momentary relay does not remain on. Only a latched relay remains on. If you want a latched relay, you must activate it from the GPI
Menus.
ACTIVATING RELAYS FROM THE GPI MENUS
You can activate relays from the GPI Menus as momentary or latching. A momentary relay goes on briefly and then turns off. A latched
relay remains on until you turn it off.
