Technical data
1. 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.
2. Time ranges Adjusment range 2s 5min (use for mode B only) 2s fixed t1 (for parallel operation) t2 (offset timing)
