| | | Applications • Designed for use with 300-BT Series GuardSwitch • Space saving profile • Requires both normally-open and normally-closed inputs • Inhibits machine restart in case of component failure • Low current for longer GuardSwitch life • DIN Rail or panel mount • LED power indicator • Manual restart only | | |
| | | The safety monitor relay INT-22.5-024 is used to monitor switching elements on guards or protective installations, and to generate a safety output signal (enable). Depending on the type of construction, the protective installation can be defined as: protective gate, protective door, housing, cover, enclosure, shield etc. The INT-22.5-024 meets the requirements of EN 201 and EN 422 Type I & II. Sensors and a safety switching device (analyzing unit) form the safety circuit for "non-contacting position switches with safety functions" in accordance with DIN VDE 0660 Part 209 and EN 61496-1. After the supply voltage has been applied to terminals A1/A2 the starting inhibiting circuit prevents an unintentional start-up of the safety relay. The device can be enabled after the start-up test has been preformed by opening and closing the guard door or gate. With this operation the simultaneous activation of both switching elements is tested. If the test is passed the device is only enabled when the guard door or gate is closed and the feedback circuit is closed as well. If a malfunction occurs in the external contactors connected to the item, the feedback loop at terminals Y1/Y2 can prevent the INT-22.5-024 from being enabled. It is possible to recognize any manipulation and failure in the safety circuit. The INT-22.5-024 is equipped with four removable terminals. This feature allows a quick installing/removing operation. The terminal locations are coded and not interchangeable. The position of the door or gate is checked by means of the cross monitoring feature via the two channels S13/S14 and S21/S22. After the supply voltage has been applied, the starting inhibiting circuit prevents an unintentional startup of the safety monitor/relay. | | |
