O p e r a t i o n 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. -
Page 21: Process Ok Lamp (Process Monitoring Step 1, Optional)
+24VDC at PIN2 for at least 100 ms starts the demagnetization. For continuous operation +24VDC 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. -

6.7 Continuous demagnetization Depending on the coil module the machine can be configured for continuous demagnetization. The configuration is set up by Maurer Magnetic before delivery. Continuous operation is controlled via D-Sub15 Control Interface. As long as +24VDC is supplied to PIN2 (Start) the demagnetization is active. When PIN2 drops to 0VDC the alternating field declines analogue to the pulse demagnetization. -
