Fuel gauge & Hour Meter with Lift Lockout Protection

Two gauges in ONE with solid state Lift Lockout feature! SenDEC’s state of the art
solid state circuitry will perform lock out under a low battery charge condition to
protect the equipment. If a lift cycle is in progress, the lockout waits until the lift
cycle is completed. The top meter is a Battery Fuel gauge that indicates the battery
charge level. The bottom meter is an Hour Meter with Flash Alert options. An
industry standard 8 pin connector is provided for easy connection. All gauges are
100% epoxy encapsulated for superb environmental durability.



Operation of the Battery Fuel Gauge:

Charge capacity is indicated using a 10 segment LED bar graph display from full (right LED segment lit) to empty (left
LED segment lit). LED Flash Alert™ flashes the 2nd LED from the left as a warning that the battery has discharged 70%.
At 80% discharge, LED Flash Alert™ flashes the left 2 LEDs to indicate very low capacity is remaining. The charge levels
and LED Flash Alert™ can be OEM customized.

Lift Lockout feature:
Under normal operating conditions the solid state contact is closed allowing normal equipment operation. When the battery
reaches a specified low charge level, the contact is opened only if the Lift is not engaged. If the lift is engaged, the meter
waits until the lift cycle is completed before lockout. The low charge level can be OEM specified. The gauge is wired by
the OEM to protect equipment during vulnerable equipment operating conditions.

Operation of the Hour Meter:
The hour meter is OEM specified and can count to 9,999.9 hours with 1/10 hour resolution, or 99,999 hours with 1 hour
resolution. SenDEC Flash Alert™ service alarms are available based on OEM requirements. The LCD is always lit, so
users can examine the total hours or if service is due at any time.


Typical Lift Lockout hookup:
814 - Wiring

Terminal assignments:
Pin 1: Hour Meter – input
Input (-). Connect to battery ground.
Pin 6: Hour Meter + input
Input (+). When positive voltage is applied with relation to Pin 1, time recording is initiated
Pin 2: Keyswitch input +
When positive voltage is applied, the LED display is lit. This may also be wired to the Pin 6 Hour Meter +
input, so when the Keyswitch is closed the Hour Meter records running time.
Pin 3, 4: Lift Lockout solid state switch
Under normal operating conditions the solid state contact is closed allowing normal equipment operation.
When the battery reaches a specified low charge level, the contact is opened only if the Lift is not engaged.
If the lift is engaged, the meter waits until the lift cycle is complete before lockout.
Pin 5: Battery – input (For Battery fuel gauge reading)
Connect as close to the battery negative terminal as possible.
Pin 7 or 8: Battery + input (For Battery fuel gauge reading)
Connect as close to the battery positive terminal as possible.
