Options D1M1, D2M2 – electric proportional control with PCOR and electric BPD
46 | © Danfoss | December 2016
D1 – electric proportional 12 V / de-energized = max. displacement
M1 – with PCOR / with electric BPD 12 V / de-energized BPD = PCOR active at port B
D2 – electric proportional 24 V / de-energized = max. displacement
M2– with PCOR / with electric BPD 24 V / de-energized BPD = PCOR active at port B
