4TD Series Digital Timers

Industrial circuit control is a snap with 4TD Series Digital Timers.Clipsal 4TD Series Digital Timers offer exceptional control of complex electrical circuits associated with

air conditioning, material handling, lighting, motor starting and process control.

These double and multifunctional devices have time ranges selectable from one second to 10 hours

and feature accuracy of 0.5%. All models are extremely compact and simply snap onto DIN rails for fast

installation. Time delays are easy to set, even after installation, because all adjustments are made on the

front fascia.

Installation Instructions

1. Select appropriate timer for application.

2. Fit timer to DIN rail.

3. Connect power supply, wire switch control input, where appropriate, load to switch terminals.

4. Adjust TIME dial to appropriate number, set ROTARY DIAL SELECTOR switches to required setting (x1/

x10 time; seconds, minutes or hours), set ROTARY FUNCTION SELECTOR switch to required setting.

NOTE:Function on 4TD4 set by connecting a wire loop.Example:4TD1 (ON D) on delay. To delay switching load by eight seconds, adjust red time dial to .8 and set

DIP switches as follows:

Function Diagram Description

ON DON delay

On application of the supply voltage, the timer starts to run.After the time t has elapsed, the relay switches ON.

ON DPON delay with

pulse control

Supply voltage must remain ON. Function is controlled by the controlinput. When the control input goes ON, the timer starts to run. Afterthe time t has elapsed, the relay switches ON. When the controlinput goes OFF, the timing run is broken and the relay trips out. Thisfunction enables control of switching delays by a small current - forexample via a sensor.

OFF DOFF delay

Supply voltage must remain ON. Function is controlled by the controlinput. When the control input goes ON, the relay turns ON. When thecontrol input goes OFF, the timer starts to run. After the time t haselapsed, the relay switches OFF. If the control input goes back to ONbefore the time t expires, the time already elapsed is cancelled andrestarts from zero on the next cycle.

INTInterval timer

On application of the supply voltage, the relay immediately switchesand the timer starts to run. After the time t has elapsed, the relayswitches OFF.

INT PInterval with

pulse control

Supply voltage must remain ON. Function is controlled by the controlinput. On a signal from the control input independent of duration thissignal pulse is converted to a fixed duration delay. Timing starts onthe positive going edge of control input, the timer starts to run andthe relay switches ON immediately. The relay turns OFF after thetime t has elapsed. During the timing period, changes to the controlinput are ineffective.

INT OFF PInterval with

OFF pulse

control

Supply voltage must remain ON. Function is controlled by the controlinput. When the control input goes ON, a defined pulse length isgenerated. Starting at the negative going edge of the control input,the relay switches ON and trips at the end of the timing run. Duringthe time period, changes on the control input are ineffective.

APRAsymmetrical

recycler, pulse

start

On application of the supply voltage, the relay cycles between ONand OFF for the preset time, beginning with the OFF phase. The ONand OFF times are separately adjustable.

ICInhibit

controller

On application of the supply voltage, the relay switches ON,regardless of the state of the control input at this point in time. Afterthat, the first positive going edge of the control input starts the timer.Each subsequent positive going edge (provided that it occurs beforethe timing run is completed) resets the timer for a further period.At the end of the timing run, the relay switches OFF. The device isthen inhibited against further control inputs. Resetting can only occurby removing and reconnecting the supply.
