2.6.3
Remote Temperature Sensors
The unit is provisioned to connect one or two remote
temperature sensor directly to the control system.
The system may be configured to display the sensor
reading in the Unit Data and to record the sensor read-
ing in the DataLink data recorder. A user specified
name may be configured for each sensor. This name
will be displayed, rather than the default Remote Sen-
sor #1 or Remote Sensor #2, name in the unit data list.
2.6.4
Fuel Level Sensor
An optional fuel level sensor (item1,
) sup-
plies an input signal to the control system as to the %
of fuel remaining in the fuel tank. The control system
will activate the A1 - “LOW FUEL LEVEL WARNING”
alarm when the level reaches 15%, and (if configured
to do so) shuts the engine down when the level
reaches 10%. The alarm is automatically cleared when
the level is brought above 25%. The fuel tank level is
displayed in Unit Data.
2.6.5
Fuel Heater
The optional fuel heater (item 3,
) applies
heat to fuel in the fuel filter. Heating the fuel dissolves/
prevents paraffin wax crystals (and ice) that form when
diesel fuel is chilled thus enabling the water separator
to work more efficiently and to prevent the filter from
plugging with wax and/or ice crystals.
When the ambient air sensor is reading 68°F (20°C) or
lower, the control system will enable this circuit. The
circuit is disabled when the ambient air sensor reading
rises to 77°F (25°C) Also, the heater is fitted with an
internal temperature switch which will close, on a tem-
perature fall, to energize the heater element at tem-
peratures below 45°F (7.2°C) and opens, on a
temperature rise, to de-energize the heater element at
75°F (23.9°C).
2.6.6
Electric Fuel Pump
The optional electric fuel pump (
at the fuel tank location and assist the engine mounted
mechanical pump in transferring fuel from the tank to
the engine. The pump is activated by the control sys-
tem whenever the engine is operating.
2.6.7
Remote Panel
The unit may be fitted with an optional remote control
panel. The remote panel, which is very similar to the
main control panel, displays compartment setpoints,
compartment temperatures and operating modes
(heat, cool or defrost).
The setpoint may be modified and the unit may be
started and stopped using the remote panel.
This compact remote panel can be mounted to suit the
individual operator’s preferences
−
on the front bulk-
head, or in the compartment (including in the wall
itself). Remote Panel keys, softkeys and alarm indica-
tors are in the same locations as the main APX display
module.
