Precautions and Warranty
Grid time lag switches (2-wire versions)
GRTL MK GRTL CB GRTL EU
GRTL MK ILM GRTL CB ILM GRTL 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.
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connectingthese
devicesinparallelorbyconnectingDANLERSmatchingslaveswitches,
availableas:SSGSMK,SSGSCBandSSGSEU.
DANLERSgridtimelagswitchescanswitchupto6amps(1500W)of:
• Fluorescentlamps,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:
• GRTLMK(ILM)  35mm(minimum)
• GRTLCB(ILM)  40mm(minimum)
• GRTLEU(ILM)  35mm(minimum)

Loading
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.
Slave switch does not operate the time lag switch:
• EnsureonlyDANLERSslaveswitchesareused
• Ensureslavewiringislessthan10mlong.
Load latched either on or off:
• Faultdevelopedduetoonover-voltagespike.
Does not work with existing 2-way switches:
• Timelagsandslavescanusethewiringoftwoway(and 
 intermediate)systems,butcannotbemixedwithsuchsystems.

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(2-wireversion)shouldbeconnectedas:
L Live
SL SwitchedLineoutput
S Slaveconnection
3.Existingtwo-waystrapperlinescanusuallybeusedtoconnectthese
timelagswitchesinparallelortoconnectslaveswitch(es),asshown
inthewiringdiagramsopposite.
4 Whenthesedevicesarewiredinparallel,dependantontheload,it
may not be possible to immediately re-trigger the time lag.
5.ThetwoterminalsonDANLERS Slave Switches are labelled:
Grid Slaveswitches: L,S
PlatedSlaveswitches: Pushbutton
The terminal connections are interchangeable.
6.Thetimelagisadjustedviaaspindlelocatedonthebottomedgeof
thedevice,asshownbelow.
7.Whenwiringhasbeencompletedandveried,switchonsupplyand
test operation.
