The last digit on the right blinks up and
down indicating the hour-meter function.
The hour-meter cannot be reset.
Grounding P1-E thru an oil low pressure
switch can stop the hour-meter. If P1-E is
not grounded then the hour-meter will run
continuously with the key on. To provide a
true engine running hour-meter an
external low oil pressure switch is
normally used. The low oil pressure switch
is closed connecting the pin to ground.
The hour meter is not running. When the
engine is running the normal high oil
pressure opens the low oil pressure switch
allowing the hour-meter to operate.
Over Speed condition
An over-speed condition will ground P1-C
(maximum 40 milliamp load) on the
speedometer when a pre-set speed has

by the customer to activate a warning

Maximum Saved Speed
This speedometer will also record the
maximum speed under normal conditions.
The maximum speed is displayed and
changes as the speed is increased over the
current maximum.
The maximum speed can be reset by
pressing the push-button for 4 seconds.

keep track of and indicate when a service
interval has passed. The interval can be
either or both mileage and hours.
A seven digit display readout displays the
total mileage, the trip mileage, hour-meter
or maximum saved speed (cleared by
pressing and holding the push-button for 4
seconds while in the maximum speed

pressing and releasing the push-button on
the speedometer.
If a service interval has been passed the
display will show a service message (one
time only).

Pressing the push-button will return the
display to the primary mileage and hour
displays.
The service interval message will also show
once every time the speedometer is
powered up. The display can be cleared by
the push-button. The pulses per mile output
from the sensor to the speedometer can be
