DOL starters [t-head2-pg]
The SmartWire module for DILM controls the contactor so the terminals A1-A2 must not be wired. Also a return signal is fed back to the SmartWire system via the SmartWire module for DILM.
The terminals X3-X4 are supplied with a bridging connection. If in the application electrical interlocking is required the bridge can be removed and the floating contacts connected.
A return signal to the PLC is available at terminals X1-X2. When required, a floating auxiliary contact of the PKZ motor-protective circuit-breaker can be connected here.
