TERMINAL ASSIGNMENT
Pin 7 or 8
= B.
Single voltage models
: Pin 8 to b; Pin 7, open.
Dual voltage models
:
When vehicle voltage is the higher voltage of the 2 operating voltages, Pin 8 connects to b; Pin 7,
open. When vehicle voltage is the lower of the 2 operating voltages, Pin 7 connects to b, Pin 8,
open.
The discharge indicator uses Pin 7 or 8 for its battery state-of-charge measurements. Connection are to
be made as close as possible to battery to prevent voltage drops that will cause errors in discharge
indicator readings. The connection is not to be switched by the vehicle’s keyswitch.
Pin 5 = Battery –
Connect to battery ground as close to battery
as possible.
Pin 2
= Keyswitch. The keyswitch turns on and off the LED display of the battery discharge indicator.
Monitoring of the battery continues when Pin 2 is turned off and the display is not lit. The hour meter
display is unaffected by Pin 2, although it cannot accumulate more time as long as the keyswitch pin is
not energized. The control inputs HRM (+) and HRM (–) are enabled by the keyswitch. Pin 2 is
connected to the vehicle’s keyswitch.
Pins 1 & 6
= Hour Meter Control. In normal operation, Pin 1 or 6 is connected and the other is left open.
Only one of these pins is connected when using normal hour meter function. It is possible to or the hour
meter between the two inputs so that it accumulates the total time either system is on. Hour meter
control logic is detailed in Table 2.
Pin 6
= Hour Meter +. HRM (+) (for use with a switched positive voltage). Pin 6 connects to a high
voltage as defined in Table 1. to activate the hour meter. Leaving Pin 6 open or connecting it to a low
voltage gives control of the hour meter to the Hour Meter (–) input. See Table 2.
Pin 1
= Hour Meter –. HRM (–) (for use with a switched ground). Pin 1 connects to a low voltage level as
defined in Table 1 to activate the hour meter. Leaving Pin 1 openor connecting it to high voltage gives
control of the hour meter to the Hour Meter (+) input.
Pin 3
= Relay. Pin 3 connects in series with the lift coil circuit (or the circuit to be switched at empty). For
holding relay (J), Pin 3 must be electrically closer to b than Pin 4
Pin 4
= Relay. Pin 4 also connects in series with the circuit to be switched at empty.
