TLS-GD2

Description

The TLS-GD2 is a positive-mode, tongue-operated guard-locking interlock switch that locks a machine guard closed until power is isolated while the guard is open. The TLS-GD2 head has two entry slots and can be rotated to provide four actuator entry points. A blanking plug is provided to seal the unused slot.

Power can only be restored through the guard after a signal is applied to the TLS-GD2’s internal solenoid to release the locking mechanism. Therefore, the TLS-GD2 is ideal for machines which do not stop immediately or where premature interruption of the machine could cause damage to tooling and components or cause an additional hazard.

The TLS-GD2 is available in three types. The TLS-1 GD2 and TLS-3 GD2 incorporate a power-to-release function. Three manual release points with security screws allow the locked TLS-GD2 to be released in emergencies. An optional lid-mounted key-release style can also be supplied. The TLS-2 GD2 has a power-to-lock function. Each type of switch has five sets of contacts of various forms and are suitable for use with PLCs.

The TLS-1 GD2 and TLS-3 GD2 are both available with Escape Release options. They are intended for machine guarding with full body access. The switch is installed so that the escape release push button on the rear side is accessible from inside the hazardous area. This allows the intentional unlocking of the TLS-GD2 from inside a hazardous area, providing a means of escape for a person who may become trapped.

A stainless-steel actuator guide is fitted to protect the unit from actuator damage due to poor guard alignment or guard wear.

	WARNING:	To monitor independently the safety contact(s) and the solenoid feedback (TLS 1, 2 and 3):
		• The 12-wire cordset 889M-F12AH-¬  must be used AND
		• For the TLS1 and TLS2: the jumper between 12 and 41 must be removed • For the TLS3: the jumpers between 12 and 41 and 22 and 51 must be removed

	WARNING:	Monitoring of safety contact(s) and the solenoid feedback (in series) is available, when jumpers are in place:
		AND
		• For the TLS1 and TLS2: by using pins 4 and 6 on the 12-pin, M23 receptacle or Pink and Yellow wires on the 12-wire cordset (889M-F12AH-¬ ) • For the TLS3: by using pins 4 and 6 and pins 7 and 8 on the 12-pin, M23 receptacle or Pink and Yellow and White and Red/Blue wires on the 12-wire cordset (889M-F12AH-¬ )
