Chapter 3: Mounting and Wiring
This section contains pinout diagrams for each module. System wiring diagrams follow.
Controller Module (FMMP01)
The controller has two connectors: a D9 connector (J1) for RS-232 and RS-485 serial
communications, and a program lockout connector (J2) intended for a keyswitch. (See Figure
3-2). Making connections to both connectors is optional. However, the program lockout
connector must be jumpered to allow the unit to enter program mode. J2’s input rating is +5
VDC maximum dry contact or open collector (drain) only. Actuation voltage must be less than
+1.0 VDC at 0.2 mA. The terminal wire size is No. 22-12 AWG.

NOTE: The controller’s program lockout connector (J2) must be jumpered to allow the unit
to enter program mode.
Relay Output Module (FMOR01)
The relay output module contains two overtravel limit relays. Each relay contains a N.O. contact
pair and a separate N.C. contact pair. (See Figure 3-3). The relay contacts are rated at 8 amps
250 VAC, 30 VDC, 1/4 HP 125, 250 VAC. The terminal wire size is 22-12 AWG.
