Precautions and Warranty
Grid time lag switches (3-wire versions)
GRTLA MK GRTLA CB GRTLA EU
GRTLA MK ILM GRTLA CB ILM GRTLA EU ILM
DANLERSgridtimelagswitchesaresuitablefortting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.

Troubleshooting

Installation Procedure
1. Pleasereadthesenotescarefullybeforecommencingwork.
Incaseofdoubtpleaseconsultaqualiedelectrician.
Makesurethepowerisisolatedfromthecircuit.
2. Thegridtimelagswitch(3-wireversion)shouldbeconnectedas:
L Live
N Neutral
SL SwitchedLineoutput
3. Existingtwo-waystrapperlinescanusuallybeusedtowirethese
devicesinparallel,asshowninthewiringdiagramsopposite.
4. Thetimelagisadjustedviaaspindlelocatedonthebottomedgeof
thedevice,asshownbelow.
5. Whenwiringhasbeencompletedandveried,switchonsupplyand
test operation.
