Analog Timer Units
Components and Switch Settings
Internal variable resistor
•
Sets variable resistance of specified
timer setting.
•
The settings of these resistors are
only effective when the selector
switch on the Unit is ON (set to the
right).
•
Numbers 0 to 3 correspond to timers
T0 to T3, respectively.
•
Set or adjust times using the flat-
blade screwdriver supplied with the
Unit. turning the variable resistor
clockwise to increase the time value.

Note 1. When the internal variable resistor is used, make sure that the external
variable resistor connector for the same timer number is open. Otherwise
the internal variable resistor settings will not function properly.
2. Use AWG 28 to AWG 22 lead wires for the external variable resistor con-
nectors.
3. Soldering is not required to wire the external variable resistor connectors.
Wire the connector as shown in the following diagram.

Timer status indicators
The SET indicators in the top row light when the corresponding
timer is operating and the TIME UP indicators in the bottom row
light when the corresponding time is up.

Each timer uses 2 pins. The upper 8 pins 8 to 1 are used for
3
timers T0 to T3 as follows:
(0: OFF, 1: ON)

External variable resistor connectors
•
Cable connector for when timer is set with external volume
instead of internal volume.
•
Turn OFF (set to left) the Internal/external volume selector
switch.
•
Numbers 0 to 3 correspond to timers T0 to T3.
•
The external volume resistance is 20 kΩ.
•
Use the following connectors. The C4K-CN223 (2 m) connector
with cable can also be used.
