Power units 05.01
The trimmer (7) "full wave" on the front panel can be used to adjust the thyris-
tor power unit so that the 100% (full wave) firing point is reached at the maxi-
mum output signal of the preceding controller.
h Apply the maximum controller output signal
h Turn the "full wave" trimmer clockwise or counter-clockwise until the green
LED for "full wave" just light up in phase-angle control, and does not light
up in burst-firing mode.
When using a logical control output (e.g. from a single-setpoint
controller) the "full wave" trimmer must be turned fully clockwise.
h Turning the "full wave" trimmer counter-clockwise limits the maximum
power output of the thyristor power unit.
When using the free-running economy circuit, both thyristor power units
must be adjusted as described above.
When using the master-slave economy circuit, the adjustment is only made
on the master power unit.
