ALARM (F1): Displays the reason for any alarm condition (last/newest alarm) when the key’s LED indicator is illuminated. Press the Scroll down arrow (diamond key) to display additional alarms. OVERSPEED TEST ENABLE (F2) : Permits the speed reference to be raised beyond the maximum controlling speed setpoint to test either the electrical or mechanical overspeed trip. F3 (function key): Programmable function key for enabling or disabling programmable control functions. F4 (function key): Programmable function key for enabling or disabling programmable control functions. EMERGENCY SHUTDOWN BUTTON: Large red octagonal button on the front of the enclosure. This is an Emergency Shutdown command for the control. Watchdog Timer/CPU Fault Control A watchdog timer and CPU fault circuit monitors the operation of the microprocessor and microprocessor memory. If the microprocessor fails to reset the timer within 15 milliseconds of the last reset, the CPU fault-control will activate the reset output. This resets the CPU, de-energizes all relay outputs and turns off all milliamp outputs.

This chapter provides instructions on how to mount and connect the 505E into a system. Hardware dimensions, ratings, and jumper configurations are given to allow a customer to mount, wire, and configure the 505E package to a specific application. Electrical ratings, wiring requirements, and options, are provided to allow a customer to fully install the 505E into a new or existing application. Mechanical Data and Hardware Installation If so labeled on the enclosure, the 505E is UL/CUL listed for use in hazardous locations in UL file E156028. This Equipment is suitable for use in Class I, Division 2, Groups A, B, C, and D (Class I, Zone 2, Group IIC) or non-hazardous locations only. This equipment is suitable for use in European Zone 2, Group II environments per compliance with EN60079-15, Electrical apparatus for explosive atmospheres – Type of protection ‘n’ These listings are limited only to those units bearing the certification identification.

 Field wiring must be rated at least 75 °C for operating ambient temperatures expected to exceed 50 °C. Wiring must be in accordance with North American Class I, Division 2 or European Zone 2 wiring methods as applicable, and in accordance with the authority having jurisdiction. Peripheral equipment must be suitable for the location in which it is used. WARNING Explosion Hazard–Do not connect or disconnect while circuit is live unless area is known to be non-hazardous. Explosion Hazard–Substitution of components may impair suitability for Class I, Division or Zone applications. AVERTISSEMENT Risque d’explosion–Ne pas raccorder ni débrancher tant que l’installation est sous tension, sauf en cas l’ambiance est décidément non dangereuse. Risque d’explosion–La substitution de composants peut rendre ce matériel inacceptable pour les emplacements de Classe I, applications Division ou Zone. WARNING Do not use any test points on the power supply or control boards unless the area is known to be non-hazardous.
