6.3.5 Process OK lamp (Process Monitoring Step 1, optional)
Process Monitoring Step 1 monitors the current and the
Process OK
lamp indicates when the
target value is reached. It goes out after pulse completion simultaneously with the
Active
lamp.
If the current remains below target value, the
Process OK
lamp remains dark.
6.4 Sensor connection M12
The sensor connection allows a simple automatization without centralised control. A sensor
(light barrier, proximity sensor, etc.) is directly connecting to the power module without
additional power supply. The sensor is positioned, so that the pulse is triggered when the object
is located inside the coil. More information about demagnetization see manual coil module.
6.5 D-Sub15 Control Interface (isolated)
Interface signals maximal current load 100mA.
D-Sub15 PIN14/15: 0...10 VDC Output maximal current load 1mA.
Do not connect D-Sub interface to a PC verbinden. PC and power module may be
damaged.
The machine can be fully controlled and monitored via D-Sub15 Control Interface. The
interface (except PIN14/15) is electrically isolated and requires external power supply.
6.5.1 Configuration D-Sub15 connector
See appendix for the configuration of the D-Sub15 connector.
6.5.2 PIN2 Start
+24VDC at PIN2 for at least 100 ms starts the demagnetization.
For continuous ope24VDC is fed constantly. Continuous operation requires a special
configuration by Maurer Magnetic. See chapter Continuous Demagnetization.
6.5.3 PIN3 Ready
+24VDC at PIN3 indicates readiness of the machine.
6.5.4 PIN4 Fault
Occurance of a fault during a demagnetization pulse results in immediate pulse
disruption. Parts in the vicinity of the coil are magnetised and need to be
demagnetised once more.
+24VDC at PIN4 indicates an error of the inverter.
A flashing
Fault
signal (~5Hz) indicates over temperature of the coil. Operation is no longer
possible. After cool-down, pulse triggering is enabled again.
6.5.5 PIN5 Active
+24VDC is present at PIN5 during a demagnetisation pulse.
A flashing (~5Hz)
Active
signal warns of high coil temperature.
