OPERATING RELAYS
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 W and X.
There are two ways you can operate relays from the KBD960.
ACTIVATING RELAYS USING F12
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 momen-
tary relay goes on briefly and then turns off. A latched relay remains on until you
turn it off.
Momentary
To activate relay contact 4, for example, follow these steps:
1. Go to Main Menu 1 and enter 1 (GPI). GPI 1 is associated with relay contact 4.
Refer to Table C.
2. Select
GPI
to bring up GPI Menu 1. This menu displays auxiliaries 1-4.

Latching
To activate the same relay as latching, follow these steps:
1. Go to Main Menu 1 and enter 1 (GPI).
2. Select
GPI
to bring up GPI Menu 1.
3. Select
MTRY
so that it is not highlighted. When

is not highlighted,
any relay you activate latches (remains on).
4. Select

and then the highlighted auxiliary icon to turn off the latched
relay.

the relay unit whenever you activate a
momentary or latching relay contact.
