8.10 Switch circuit
TA shift, TC shift and unit No. are changed over by the
switch.
TA shift and TC shift are set in factory with unit No. at "1".
In servicing, the setting should be made to the same
TA/TC shift as the PC board attached originally.
In case of operating one single unit, unit No. "1" will do.
With the operation of many units (multi units control) the
unit No. should be adjusted in such a way as 1, 2, 3 ........
