6.1.2 Integration in production line
Cycle times below specification may lead to overheating of the coil. Pulse triggering
is blocked („Ready indicator dark / no „Ready“ signal, Alarm lamp red / Alarm signal).
After cooldown pulse triggering is enabled again.

6.2 Controls
6.2.1 Main switch
Only switch off machine during demagnetization pulse in case of an emergency.
The machine is turned on/off with the main switch.
6.2.2 Start/Pulse button
The white button
Start
/
Pulse
triggers a demagnetization pulse.
6.3 Indicators
Troubleshooting and analysis in chapter troubleshooting.
6.3.1 Operation lamp
The
Operation
lamp indicates an active 24VDC power supply.
6.3.2 Ready lamp
The
Ready
lamp indicates readiness of the power module to trigger a pulse.
6.3.3 Fault lamp
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.
The
Fault
lamp indicates an error of the inverter.
A flashing
Fault
lamp indicates over temperature of the coil. Operation is no longer possible.
After cool-down, pulse triggering is enabled again.
Further Information in Chapter Troubleshooting.
6.3.4 Active lamp
The
Active
lamp is lit during a demagnetisation pulse.
A flashing
Active
lamp warns of high coil temperature. Demagnetisation pulse is possible.
