Function One of two redundant motors will operate on demand signalised by input Y1. Successive requests will operate the motors in an alternating sequence (sharing the duty between the devices). On demand both devices (pumps) will operate in parallel: Mode A (parallel operation by separate input signal): Input Y2 initiates parallel operation. Without signal at input Y2, only one single motor will operate at each request. Mode B (parallel operation by timing): If an operation request on input Y1 exceeds the ajdusted delay, the unit will start the second motor for parallel operation. 6.

The Pump-Alternator is sensitive to one (mode B) or two (mode A) digital input signals. Each of the two output relays activates one of the two devices (usually pumps or motors) driven. The two outputs (Rel.1 and Rel. 2), are equally configured and interchangeable. In case of request for operation (Y1-Y3 linked by external contact) one of the output relays energises as long as the signal persists on input (Y1). Next time there is a request for operation the alternate output operates in the same manner. This way both connected devices (pumps or motors) will share load. The information about,...
