, CAUTION
Be cautious when working around and connecting to the LM
Series’ terminals, especially those other than the positive
terminal (+) as there is no electrical protection on the negative
(-), reset, enable, and/or backlight terminals.
INSTALLATION
For specific model instructions, see steps below for model-spe-
cific processes and Figure 8 for visual aids.

WIRING INSTRUCTIONS
Included with the LM Series hour meters are 16 ga, black PVC
covered per GM spec 59072-R terminals wires (Honeywell part
number 4685) (See Figure 4). The quantity of wires included with
the LM Series hour meter is identical to the number of active
terminals on the hour meter (either 2, 3, or 4). An equivalent wire
may also be used.
If the hour meter is mis-wired, no product damage will occur
under any mis-wired condition.
FIGURE 1. WIRING DIAGRAM
Pin + V+ operating voltage
Pin - V - common (ground)
Pin E Enable (use operating voltage to power this pin to
record elapsed time)
Pin R/B Backlight or reset to zero
ACTIVATION
Two-terminal hour meters will always record time once power has
been applied. For LM Series hour meters with three or four active
terminals, enable power on by the positive contact and the de-
vice will continuously record. Hour meters with four terminals will
become backlit once the backlight terminal connects to positive
contact.
RESETTING THE DEVICE
To reset the Honeywell’s LM Series hour meter’s digits to zero,
connect the “R” terminal to positive. This action should be ap-
plied for at least one second to avoid mis-operation.
