Installing the Programmer (Fig. 3)
Open the master switch.
Make sure no subbase wiring is projecting out beyond
the terminal blocks. Tuck in wiring against the back of
the subbase so it does not interfere with the contacts.
Grasp the handle of the programmer chassis and
engage the chassis hinge brackets with the pivot pins
at the bottom of the subbase.
Swing the chassis inward until the spring connectors
engage the knife-blade contacts. Push in until the
contacts are fully engaged.
Tighten the chassis retaining screw securely.

Removing the Programmer

Open the master switch.
Loosen the chassis retaining screw.
Pull outward on the handle.
Disengage the chassis hinge brackets from the
subbase pivot pins.

Normal
Operation
13-L2 Firing rate motor drives closed;
line voltage at terminal 13 after
motor closes.
13-L2 Firing rate motor drives closed;
line voltage at terminal 13 after
motor closes.
— 1. Raise setpoint of Series 90
Controller—firing rate motor
should drive toward open.
2. Lower setpoint of Series 90
Controller—firing rate motor
should drive toward closed.
— If damper control is used,
actuator drives damper open.
13-L2 If damper control is used,
spring return drives actuator
and damper closed; line
voltage at terminal 13 after
actuator closes.
CAUTION
After completing these tests, open the master switch and remove all test jumpers from the
subbase terminals. Also remove bypass jumpers from the low fuel pressure limits (if used).
