5.2 PROGRAM LOCKOUT OPTIONS
5.2.1 PROGRAM LOCKOUT KEY OPTION
A PROGRAM LOCKOUT (25) key switch can be ordered as a factory installed option. It
may also be added later by the customer, if desired. To install the key switch, remove the
hole plug from the lower left corner of the front panel and mount the switch using the nut
provided. Plug the wires from the switch onto the mating two prong connector on the back
of the control circuit board.
Mounting the key switch will be easier if the front panel control circuit board assembly is
removed from the enclosure. Remove the four mounting screws from the front panel and lift
it off of the enclosure.
To put the control in the PROGRAM mode using the PROGRAM LOCKOUT Switch:
Rotate the key 45 degrees clockwise and hold; While holding the key in this position,
press and release the PROGRAM/OPERATE push-button, and then release the key.
The OPERATE LED will now turn off and the PROGRAM LED will turn on, indicating
programmability of all functions.
To put the control in the OPERATE mode:
Press the PROGRAM/OPERATE push-button again. The control will return to the
OPERATE Mode without the necessity of rotating the Key.
