3 Otherwise, the timermay malfunction or be sure to turn off the powersupply to the Timer beforechanging any of the This Timer should be wired by qualified personnel according to the National Electrical Code (NEC) and local Do not connect input or contact terminals to voltages higher than those indicated on Protect the coil and load circuits with properly rated Do not install in damp or moist Any application of this Timer should be designed to prevent bodily injury, or property damage, in the event of product failure or normal wearout of this Voltage or Dry ContactThe inputs (Start, Reset, Gate,and Check) on this Timer areconsidered a no voltage or drycontact thus requires no externalvoltage source to activate. Simplyconnecting them to the commonterminal (Pin 3 or 15) via a switch,relay contact, open collectorsensor, and etc.

In Repeat Cycle mode,the check input allows the Timer tobe used like a binary flip-flop oralternating relay. CAUTION!

When makingyour choice the operation modewill be displayed in the operationmode display eight operation modes are: Mode Operation A ON-delay B Repeat (50% fixed duty cycle) C Signal Interval/OFF-delay D Signal OFF-delay ( l ) E Interval F Cycle One-shot G Signal ON-delay/OFF-delay H Signal OFF-delay ( ll )Note:The operation mode is fixed to "A"in type h3ca -8 and thru the operation andapplication sections of thisinstruction manual to determinethe proper function selection foryour application.

7 To insure properoperation, the supply voltageshould be disconnected beforechanging A ON-delay(Power-ON Start/Power OFFR eset): Connect start terminals (3& 6). Upon application of power tothe Timer , time delay periodbegins. At the end of time delayperiod, output contacts switches,either connecting or disconnectingload. Output remains switcheduntil power is removed or a resetinput is 1 Mode A ON-delay(Signal Start): Power is appliedcontinuously. Time delay periodbegins at the leading edge of startinput. Output contact switcheswhen the accumulated time equalsthe set time. Subsequent startsignals during or after timing willnot be accepted. The output relaywill remain switched until a resetinput is applied or power 2 Mode B Repeat Cycle - SignalStart (50% fixed duty cycle):Power is continuously OFF/ON cycle is initiated atthe leading edge of the start output relay will be OFF forthe set time and ON for the settime.

8 The ON and OFF cycle willcontinue to alternate until a resetinput is applied or power 3 Mode B Repeat Cycle - PowerON Start/Power-OFF Reset(50% fixed duty cycle): Connectstart terminals (3 & 6). Uponapplication of power to the Timer ,the OFF delay is initated for theset time and then ON for the settime. The ON and OFF cycle willcontinue to alternate until a resetinput is applied or power 4 Mode CSignal Interval/OFF-delay:Power is continously delay period begins on boththe leading and trailing edges ofthe start input. Output contactswitches during time delay period,either connecting or disconnectingload. Once the Timer has timedout from the trailing edge, it resetsand is ready for subsequent startinputs.
