T

he Multi-Mode Timer V133 features aneasy-to-read circular scale LCD display,and simple set-up through a singlemulti-function knob. The V133 is quickly installed in a stand-ard 72 instrument cut-out, usingspring clips. Connections are madethrough rear screw terminals. The unit can alternatively be DIN rail mounted using an optional adaptor base. Timing can be initiated either by switch-ing on the power supply, or by externalcontact across terminals B1-B2.These modes are selectable by shorting / opening terminals X1-X2.Models V133L and V133TL have aback-lit LCD display.Models Ri is energised when B1-B2 contacts areclosed, and de-energised when thesecontacts are opened. Timing starts whenB1-B2 contacts are toggled from closed to open. Rd acts as before. In Model and the Timer is re-set when power isswitched off. The Timer is now ready foruse.The V133 with X1-X2 closed, and Model V133T with X1-X2 open or closed,timing is not aborted when power fails. The elapsed time at instant of power failure is memorised. When power resumes, the timing startsfrom the interrupted point.The display of the V133T remains onwhen power fails, for up to 5 days. Its battery recharges in approximately 24 hours. V133 can set up for either single-range of multi-range operation. For this,the knob should be pressed for about 8seconds when switching on the in- strument, until the time units blink in the centre of the display. In this mode, asingle time range can be selected. Delaysettings then can be made only withinthe selected range: i.e., the timer will not jump to the next higher range if a delay setting exceeds the selected range. If all ranges are simultaneously selected, delay settings can freely be made for any time value, spanning all time ranges.A time delay setting can be changedeven while timing is in progress. The elapsed time is indicated by a blink-ing segment on the circular scale. The switching state of the the Time Delay Relay (Rd) is indicated by a relay symbol on the LCD display. If the knob is pressed for a longer duration and then released, the settings are protected against any changes. This secured mode is indicated by a small lock symbol on the LCD display. Unlocking can be done the same way. V133 and V133T have 2 oper-ating modes, selected by opening / short-ing terminals X1-X2. With X1-X2 open, V133 and V133T function identically.Instantaneous Relay (Ri) is energised andtiming starts as soon as power is switched on. The Time Delay Relay (Rd)remains de-energised until the pre-settime ends, at which instant it is energised.Rd is deenergised again when power isswitched off. In the

Functions

V133 , the timingcycle is aborted if power fails before thepre-set time ends. In the T-Versiontiming can be re-set by closing B1-B2.In the V133T , with X1-X2 closed, V133 , with X1-X2 closed, Ri isenergised, and timing starts as soon as B1-B2 contacts are closed. Rd acts as before. In the

Operation

Changes in settings are possible onlywhen power supply is on. Pressing the knob briefly causes the inner circle of numbers to blink. The pre-set time is displayed on the circular scale, and can be changed by rotating the knob. Pressing the knob again causes the pre-set time to blink. The desired time rangecan be selected by repeatedly rotating and pressing the knob.The time range and pre-set time delay settings are protected against power failure. New settings are memorised,
