Specifications for Start, Gate, Reset Signal (Cat. Nos. 700-HR52, -HRT6, -HRV, -HRQR)
Start, Reset, and Gate signals are typically contact closures or signals from a solid-state sensor.
(R) Reset Signal
The reset signal is not required for normal operation. Reset
can be accomplished by removing power from the timing
relay. To reset the timer without removing power, a signal
must be applied which resets the timing cycle and returns
the output contacts to their shelf state. The reset signal will
override both the start signal and gate signal. The reset
signal can be either momentary or maintained.

(G) Gate Signal
The gate signal is not required for normal operation. The
gate signal provides a pause or retentive timing function.
When the gate signal is applied the timing cycle is
momentarily interrupted. When the signal is removed, the
timing cycle resumes timing at the point the cycle was
interrupted and will continue timing until the time delay is
completed or the gate signal is re-applied.

Contact Signal — Cat. Nos. 700-HR52, -HRT6, -HRQR
Contact closure provides signal to timer. A low energy signal
is generated by the 700-HR timing relay. For optimum
reliability, use contacts designed for low energy switching
(5V, 1 mA) (Bul. 800F-X__V, 800T-X__V). No external voltage
should be connected to the contact signal.
Contact Signal — Cat. No. 700-HRV
For use in applications where it is not possible to use
contacts designed for low energy switching. Contact closure
provides signal to timer. A signal is generated by the 700-HR
timing relay, and is the same potential as the supply voltage
of the timing relay. No external voltage should be connected
to contact signal. 700-HRV52TU24 supply voltage: 24...48V
AC, 12...48V DC / 700-HRV52TA17 supply voltage:
100...240V AC, 100...125V DC.
Solid-State Signal — Cat. Nos. 700-HR52, -HRT6
Timing relay is suitable for use with a 3-wire NPN 12...24V
DC sensor. Supply voltage potential of sensor must be
the same as the supply voltage potential of the timing
relay. Permissible off-state leakage current from sensor:
0.01 mA max.
