Features
- Dosage is lowest when the signal is 4 mA from the valve and highest when the signal is 20mA from the valve with a straight-line variation in between.
- Auto/Off/Manual selection switch with indicator lights.
- Built in circuit protection with easy access panel mounted fuse.
- Clear hinged cover over controls for protection against water and dust ingress.
- Optional External Pacing option - i.e. actuation via an impulse water meter - with stop function. The stop function accepts an input from a level switch in the chemical holding tank such that the pumpwill cease operating should the level switch indicate that the chemicals have run out. *Optional 4 to 20mA signal actuation with stop function. This offers that ability to accept a signal for an external piece of equipment - e.g. some boiler modulating feed valves emit a 4 to 20mA signal, which can be used to ensure that dosage of chemicals varies in direct proportion to the flow of water into the boiler.
*NOTE: ONLY ONE OF THESE OPTIONS - NOT BOTH CAN BE UTILISED AND MUST BE SPECIFIED AT TIME OF ORDER
