Grid time lag switches (3-wire versions)

GRTLA EU ILM
DANLERS grid time lag switches are suitable for fitting into the MK
Grid Plus (MK), Crabtree grid (CB) and Eurodata plates (EU).
A short press will switch the load on and it will switch off automatically
after the time lag period has expired. The time lag can be set between
approximately 1 minute and 2 hours.
These devices need a neutral supply.
The button on the illuminated versions (ending ILM) is lit until the
button is pressed, it comes back on when the time lag has elapsed.
The load can be switched on from other locations by wiring these
devices in parallel.
DANLERS grid time lag switches can switch up to 6amps (1500W) of:
• Fluorescent lamp, either high frequency or switch start
• Incandescent or mains halogen lamps (recommended with integral safety fuse)
• Electronic or wire wound transformers
They can also switch up to:
• 1 amp (250W) of Fans or Metal Halide lamps.
The grid time lag switches need the following depth wall boxes:
• GRTLA MK (ILM)
35mm (minimum)
• GRTLA CB (ILM)
40mm (minimum)
• GRTLA EU (ILM)
35mm (minimum)

Loading
Cannot get a neutral supply to the switch:
• Consider using DANLERS 2-wire grid time lag.
Time lag switch “clicks” off but load stays on:
• Non-resistive load (contactor, emergency, CFL, LED or 2D lamp)
Add CAPLOAD across the load as shown in wiring diagram.
• Fault developed due to an over-voltage spike.
Load latched either on or off:
• Fault developed due to an over-voltage spike.
