GENERAL SAFETY
RECOMMENDATIONS
! WARNING
Disconnect power when connecting or disconnecting the timer or its loads.
! CAUTION
Do not change the time unit or time range while the timer is in operation. Otherwise, the timer may malfunction or be damaged. Be sure to turn off the power supply to the timer before changing any of the selections.
1.This timer should be wired by qualified personnel according to the National Electrical Code (NEC) and local codes.
2.Do not connect input or contact terminals to voltages higher than those indicated on timer.
3.Protect the coil and load circuits with properly rated fuses.
4.Do not install in damp or moist locations.
5.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 product.
GLOSSARY
No Voltage or Dry Contact
The inputs (Start, Reset, Gate, and Check) on this timer are considered a no voltage or dry contact thus requires no external voltage source to activate. Simply connecting them to the common terminal (Pin 3 or 15) via a switch, relay contact, open collector sensor, and etc., is all that is required to activate each input.
Gate Input (Pause)
When the gate input is closed, timing is temporarily stopped. When the gate opens, timing resumes at the point of interruption.
Check Input
When check input is used in ONdelay mode, the elapse time measurement of the set time is not performed - especially useful where ON-delay override is desired. In Repeat Cycle mode, the check input allows the timer to be used like a binary flip-flop or alternating relay.

RANGE SELECTION
There are seven different timing ranges from which to choose. Press the rightmost thumbwheel switch to select the desired time unit. When making your choice the selected time unit will be displayed in the time unit display window.
The seven time units are:

Be sure turn off the power supply to the timer before changing any of the selections.
MODE SELECTIONS
There are eight different operating modes from which to choose. Press the leftmost thumbwheel switch to select the desired operation mode. When making your choice the operation mode will be displayed in the operation mode display window.
The 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 |
FCycle One-shot
GSignal ON-delay/OFF-delay
HSignal OFF-delay ( ll )
Note:
The operation mode is fixed to "A" in type H3CA-8 and H3CA-8H timers.
Read thru the operation and application sections of this instruction manual to determine the proper function selection for your application. To insure proper operation, the supply voltage should be disconnected before changing functions.
Mode A ON-delay (Power-ON Start/Power OFF
Reset): Connect start terminals (3 & 6). Upon application of power to the timer, time delay period begins. At the end of time delay period, output contacts switches, either connecting or disconnecting load. Output remains switched until power is removed or a reset input is applied.

Mode A ON-delay
(Signal Start): Power is applied continuously. Time delay period begins at the leading edge of start input. Output contact switches when the accumulated time equals the set time. Subsequent start signals during or after timing will not be accepted. The output relay will remain switched until a reset input is applied or power is interrupted.

Signal Interval/OFF-delay:
Power is continously applied. Time delay period begins on both the leading and trailing edges of the start input. Output contact switches during time delay period, either connecting or disconnecting load. Once the timer has timed out from the trailing edge, it resets and is ready for subsequent start inputs. Refer to Figure 5.
