OPERATION
3) To operate the examination day program, set the AUTO/OFF switch of the D channel to AUTO, and those of
other channels to OFF.
AUTO
OFF
A
B
C
D
Thus, by shifting the AUTO/OFF switches different programs can be readily operated.
If exceeding per-channel program capacity of 30. When, for example, a frequently-used spot announcing
machine needs to be activated 80 times a day.
Set the rear-mounted CHANNEL ASSIGNMENT switches
of both B and C channels to ON.
AUTO
OFF
Set the front-mounted AUTO/OFF switches of A, B,
and C channels to AUTO and that of D channel to
OFF.
A
B
C
D
This expands a program capacity to 80, with 30 being programmable into A channel, another 30 into B channel
and 20 into C channel.
POINTS TO REMEMBER
1) All the indications go out at time of power outage. However, a clock works normally and stored programs are
protected. No relay output is produced. After power restoration, the timer works normally and indicates the
current hour.
2) A clock and stored programs are maintained for about 100 hours during power outage. If the clock display
flashes to indicate "0000" with beep after power restoration, this indicates that the battery has run down. In
such a case, set a clock for the current hour and register the program again.
3) The 100-hour power outage protection is subject to the battery being kept fully charged. It takes about 200
hours to fully charge the battery. Frequent occurrence of power outage shortens the 100-hour protection
time.
OUTPUT RELAY
Output is a no-voltage (dry) make contact.
The relay makes for five seconds at preset time (pulse output system).
Output relay contact capacity :
Maximum: 24 V DC 0.5 A (resistance load)
Minimum : 10 mV DC 10 µA
