Contact Cartridges

Timers are supplied with two slots for timed contacts and two slots for

instantaneous contacts. “Dummy” cartridges are placed in any unused

cartridge slots to guard against entrance of foreign material.

The N.O. cartridges, N.C. cartridges, and dummy cartridges are removable and

interchangeable using the same cartridges for both timed and instantaneous

slots, with the exception of the N.C. cartridges in the instantaneous positions

(reference Note on page 1). Use the following procedure:

1. Disconnect all power from timer or timer panel.

2. Loosen the two front housing screws (See Figure 1.) until the housing

slides back along the screws for approximately one inch. The screws are

captive and will restrain the front housing to protect the circuit cable

that connects to the timer base.

3. Remove the N.O. or N.C. contact or the dummy cartridge by lifting it

out of the slot. A screwdriver is required to pry out the dummy

cartridge.

4. Insert the desired cartridge. The cartridges are keyed and must be

inserted with correct orientation (See Figure 1.).

5. Slide front housing back down carefully to avoid cable damage. Tighten

screws.
