Control Board Power-Up
The control board can be powered (+24V) in two different ways: either 1) directly from the
power board ASIC, terminal X10; or 2) externally using the customer’s own power source.
This voltage is sufficient for parameter setting and for keeping the fieldbus active.
By factory default, the control unit is powered using the terminal X10 on the power board.
However, if an external supply is used to power up the control unit, a load resistor must be
connected to terminal X10 on the power board. This applies to all chassis ≥CH61.
Notice
IMPORTANT NOTE FOR CHASSIS CH3, CH4 and CH5: If you power
the control board from the power board be sure to connect the
cable to the correct terminal. Terminal J2 on the power board is
reserved for this purpose. Do not connect the cable to terminal J1.
See Figures 4-4 and 4-5.
