UE403, Safety Switch Amplifier for Muting The advantages of using the UE403 in conjunction with the M4000 series of light curtains are: local processing of signals (fewer cables, lower installation outlay, more control cabinet space); supply voltage for muting sensors direct from UE403; local IP65 connection makes additional control cabinet unneccessary; no reconfiguration is required when photoelectric switches are replaced. Connection of 2-4 muting sensors, external muting lamp, reset and override control switch, conveyor belt stop signal Concurrence monitoring Monitoring of total muting time Sensor gap monitoring and test Partial blanking End of muting by ESPE Integrated override Note For use with the M4000 series of light curtains UE403 to M4000.
