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
131 degrees F
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 i n ON-
delay 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.
