RES-445

Page 53

The language which is selected with step 20
in the Configuration menu remains set even if

the factory settings are restored.

Maintenance

The controller requires no special maintenance.
Regular inspection and/or tightening of the terminals –
including the terminals for the winding connections on

the impulse transformer – is recommended. Dust
deposits on the controller can be removed with dry
compressed air.
