Controlling the external fan by temperature triggered dry contact
The Temperature trigger has a user configurable range of +20°C to +55°C (68 to 131 °F). When the battery
temperature (monitored by the Battery Temperature Probe) reaches the threshold, the assigned relay closes and
turns on the external fan.
Procedure
From the Logo screen, navigate to
Control Menu
>
RELAY TEMP
. Press the
SELECT
button and the current
temperature display will start flashing. Use the
Scroll
button to change the temperature in 5°C increments. Press
SELECT
to accept the changes or
CANCEL
to abort.
Dry contact functions are not programmable through the LCD. Use the Web GUI or HyperTerminal instead.
