Precautions
Operation
The earlier ON time setting takes precedence.
If both settings 1 and 2 are for an ON/OFF or pulse operation, the
output is continuously produced without being interrupted. For ex-
ample, if setting 1 is for cyclic operation, and 2 is set for an ON/OFF
operation, the cyclic operation is performed during period of a to b,
and the ON/OFF operation is performed from b to c.
Multiple-day Operation
If more than one day is specified and when the output is turned on, it
is turned off on the day when the first OFF time is set.
If an ON and OFF have been set at the same time of the same day
(such setting is possible), no operation is performed.
If the Mode Switch is set to the P1 (or P2) position, no output is pro-
duced. Therefore, after setting has been done, set the Mode Switch
to the RUN position and confirm that the automatic operation indica-
tor lights.
The set data may be erased if the OUT switch is moved between the
TIMER and PULSE positions after the data has been set.
Backup Power Supply for Memory Protection
during Power Failure
The H5S Time Switch has a built-in battery. This backup power sup-
ply allows continuous operation of the internal timer circuit and re-
stores the user program during a power failure. If the duration of a
power failure or service interruption is within the life-time of the
backup battery, no time adjustment is required for the timer. Note
that during a power failure, the output contacts are in the OFF state,
the display is dark, and the Key switch cannot be used.
The built-in lithium battery cannot be replaced.
WARNING
!
The H5S has a built-in lithium battery. When disposing of old
batteries, or of an entire timer containing lithium battery, be
sure to do so properly. Lithium batteries may explode if inciner-
ated, causing fire or severe burns. Also, do not touch the input
terminals of any H5S Timer while power is being supplied to
the timer.
