- Page 2 TC4-T30: 24-HOUR TIMER CONTROL ΠThe TC4-T30 is a timer designed to control farm equipment. It uses an internal clock to oper- ate three timers. Each timer contains up to 24 different operation cycles. At each cycle start, the timer activates one of the three dry contacts. A skip-a-day feature is included. A four- digit display and a push-button make programming easy.
- Page 3 Two types of alarms are currently available on the market. The first type is activated when current is cut off at the source; the other is activated when current is supplied to the input. Use the NO terminal for an alarm of the first type; otherwise use the NC terminal. TC4-T30.rev.05...
- Page 4 LOCATION OF THE CONTROLS Inside Cover Front Displays the clock time and other values. Turns on when output relay 1 is activated. Turns on when output relay 2 is activated. Turns on when output relay 3 is activated. Turns on when the current time is PM in 12H. Turns on when the current day is being skipped.
- Page 5 If any changes were made within this time period, they will be recorded in permanent memory. The TC4-T30 has an internal clock used for programming the timer cycles. To display the current time, turn the selection knob to the position.
- Page 6 The TC4-T30 operates three independent timers with 24 different cycles or channels each. Each timer is connected to an output relay. A cycle is defined by specifying a Start Time along with either a Stop Time or a Running Time. The Start and Stop Times are clock times whereas the Running Time is the length of the cycle (in minutes and seconds).
- Page 7 When the Skipping LED is on, the current day is being skipped for all three timers. When the Skipping LED is off, the next day will be skipped for all three timers. TC4-T30.rev.05...
- Page 8 AUTOMATIC MODE Set the selection knob to depend- ing on the timer you are setting. The display shows “ ” where n is the timer number and “1” is the cycle number. The number “1” is flashing. Using the adjustment knob, select the cycle (or channel) number. Press the push-button once.
- Page 9 If a Running Time is de- fined for the cycle, the Running Time continues to elapse even if the timer output is temporarily deactivated. The diagrams below sum up the operation of the cycle delay for both Start/Stop Time and Start/Running Time cycle definitions. TC4-T30.rev.05...

- Page 11 Running Time or until the stop time is reached (see the diagram above where this is applied to the Manual Stop function). Note that the skip-a-day mode applies to all three timers at once. TC4-T30.rev.05...
- Page 12 ’ ALARM CONDITIONS An alarm is set off when one of the following situations occurs: the battery is low (ii) the permanent memory chip is not working properly (iii) a power failure occurs (iv) the microprocessor is defective. “ BACK-UP BATTERY A 1/2AA lithium battery is included with the timer.
