4.4.2.2 COOLANT TEMPERATURE CONTROL
The Coolant temperature control settings provide for control of coolant heaters / coolers using the Coolant
Temperature Sensor as the control input.
Outputs should be configured to Coolant Cooler Control and/or Coolant Heater Control to achieve this.
Coolant heater
control
= Coolant Heater Control function is disabled
= Coolant Heater Control function is enabled. If the engine coolant temperature falls
below the On setting, any output configured to Coolant Heater Control will be energised.
This is designed to control an external engine heater.
If the coolant temperature rises above the Off setting, the output is de-energised.
Coolant Cooler
control
= Coolant Cooler Control function is disabled
= Coolant Cooler Control function is enabled. If the engine coolant temperature rises
above the On setting, any output configured to Coolant Cooler Control will be energised.
This is designed to control an external engine cooling system, for instance an additional
cooling fan.
If the coolant temperature falls below the On setting, the output is de-energised.
Fan Control
An output configured to Fan Control will energise when the engine becomes available (up to
speed and volts). This output is designed to control an external cooling fan.
When the engine stops, the cooling fan will remain running for the duration of the Fan
Overrun Delay.
Enable or disable the
feature. The relevant values
below will appear greyed out
if the option is disabled.
