6.5.6 PIN7 Process OK (Process Monitoring Step 1, Optional)
Process Monitoring Step 1 monitors the current. +24VDC at PIN7 indicates when the target
value is reached. It falls to zero after pulse completion simultaneously with the
Active
signal
(PIN5).
If the current remains below target value, PIN7 remains at 0VDC.
6.5.7 PIN10 External enable signal
If switch
S1 Enable
is set to
EXT.
on Interface board D-Sub15. +24VDC is required on PIN10
to obtain
Ready
state.
6.5.8 PIN11 Module Ready
+24VDC at PIN11 indicates that
Coil module connector
is correctly connected and the coil
temperature is ok.
6.5.9 PIN14/15 Analogue out (Field strength proportional signal)
PIN14/15 are not electrically isolated.
We recommend using an isolating amplifier (e.g. Phoenix Contact MINI MCR-LS-
UI-UI-NC) especially with connection length >5m.
PIN14:
0...+ 10 VDC (Scale: 0…100% of maximum specified field strength)
PIN15: Reference to PIN14
0…+10 VDC at PIN14/15 indicates the current field strength of the machine. 10VDC
corresponds to the maximum specified field strength. At 0VDC the field strength is 0.
During a demagnetization pulse the signal rises from 0VDC to +10VDC and declines back to
0VDC. The
analogue out
allows monitoring the machine. The signal exhibits a slight delay.
