Controlling the external fan by temperature triggered dry contact
The Temperature trigger has a user configurable range of +20°C to +55°C (68
– 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.
1.
Assign the Temperature trigger function to an available dry contact, (for example,
c2=11
, where 11 is the
assigned index for the Temperature trigger function.)
2.
At the HyperTerminal screen prompt, type
Temp
and press Enter to display the current temperature
setting. For example, the Alpha FXM might return
*
temp=20
.
3.
To change the value to +35°C, type
temp=35
and press Enter. The Alpha FXM returns
*
temp=35
as
confirmation.
