tGard is the new innovative approach to controlling access to hazardous machinery and equipment. It is a compact metal bodied system that enables the configuration of various safety products including electrical safety gate switches (with or without guard locking), mechanical trapped key interlocks, and electrical operator controls, either as separate devices or integrated into one device.
tGard offers "a customised safety solution, as standard" and is defined by a range of tGard elements, including selector switches, safety switches (solenoid and non solenoid), personnel keys (safety keys), emergency release, push buttons, estops, indicator lamps and a choice of operating handles for both hinged and sliding guard doors. These elements are simply selected and then assembled into a robust housing, suitable for mounting onto machine guarding, providing the user with an exact configuration specific to the application.
tGard is quick and easy to install and can be mounted directly onto a flat surface, doors or extruded aluminium profiles without the need for mounting plates or brackets. It is IP65 as standard and has been designed to be fully compliant with the new machinery safety standards.
How to Configure tGard Electro / Mechanical Gate Switches?
Configuration Guideline
At the end of the selection process, the part numbers drop their “T”, except the first item. Example:
THE + TRX + TSN +TSMDL + TEC + TLG + TP6 + TG1 + T2E + TEB + TW3 = THERXSNSMDLECLGP6G12EEBW3
When creating a tGard stack, the wiring of connections follow these rules:
1. Safety circuits are in fixed positions on each connector and comprise of volt free circuits.
2. Inputs / outputs are allocated from the bottom of the stack, ascending.
3. On any one element, the input is assigned first, then the output(s).
4. Outputs are +24v, taken from the +24v supply.
5. Selection of the connector depends upon the wiring requirements for inputs / outputs / safety circuit of the total stack.
tGard High Level Coded
The High Level Coded (HLC) element for the tGard configurable access & control unit for machine guarding provides protection against defeat with a high misalignment tolerance on the actuator and provides safety outputs through OSSD or SSR configurations.
The tGard High Level Coded (HLC) element can also incorporate safety contacts from associated tGard elements.
