Fan
Logic
EMS-GC10 is able to control four different fans. This could for example, be air supply
fans for supplying air to a genset in a closed enclosure, or radiator fans for switching on
and off cooling fans for air coolers.
There are two features in the fan control of EMS-GC10.
1. Priority rearranging depending on running hours of the fans
2. Temperature-dependent start and stop
A priority routine ensures that the running hours of the available fans are evened out
and the priority shifts between them.
The functionality behind the temperature-dependent start/stop is that the EMS-GC10
unit measures a temperature for example, cooling water temperature, and based on
this temperature it switches on and off relays that must be used for engaging the fan(s).
Fan Parameters
Each fan has a group of parameters that defines their scheme of operation. It is
recommended to use the PC utility software (USW) for the setup, because then it is
possible to see all parameters. The setup of the fan control is done in the parameters
6561-6620 and by using M-logic in the PC utility software (USW).
