5.4 Supply voltage phase supervision
The supply voltage phase supervision consists of two functions:
- Missing supply phase detection
- Incorrect supply phase order
The three supply voltage phases are wired to the hoist-monitoring unit. Each time the unit is powered up,
the phase order is checked. The unit will continuously measure the existing of all three phases.
In case wrong direction of hoisting occurs (reversed phase condition), note that the two input power
wires are reversed at terminal X2A!
