Applications
- De-ice control system
- Anti-freeze control system
Features
- May use regular contactors for circuit control; or solid stat relays (SSR) if the Power Function is to be used.
- All information and control in a single compact control panel; From 14 to 46 circuits.
- Fault monitoring for each circuit, plus common alarm handling.
- User selectable delay as each circuit is turned on, automatic delay as these are turned off
- Power factor selector; user may select 50%, 75% or 100% of the circuits to be turned on
at any given time - Wake-up signal input; connect a simple temperature switch that will activate upon low temperatures,
and this will wake up a system which is turned off - External signalling for turning on or off the system, override of Power Factor or delayed intervals.
- May be used with or without buttons for individual circuit control
- Several operator panels may be connected to the system, and each will work in parallell
- An optional gateway may be installed to provide communication to an external control system,
e.g. p process control system
