Specifications
Internal variable
resistors
These variable re-
sistors are used to
set the timers. The
settings of these re-
sistors are effective
only when the cor-
responding IN/EXT
selector is ON. To
set or adjust the
time, use the
screwdriver
supplied with the
Unit. Turn the vari-
able resistor clock-
wise to increase the
time value. The
numbers 0 through
3 correspond to T0
through T3, respec-
tively.

IN/EXT selectors
When the internal variable resis-
tor is used, set the correspond-
ing pin to ON; when an external
variable resistor is used, set the
corresponding pin to OFF. Pin
numbers 4 through 1 correspond
to T0 through T3, respectively.

Indicators
The SET indicators in the top row light when the cor-
responding timer is operating. The TIME UP indica-
tors in the bottom row light when the corresponding
timer (T0 through T3) turns ON.
Time range setting
External variable resistor connectors
External variable resistors can also be used to set the
timers. The IN/EXT selector pin must be set to the
OFF position. Numbers 0 through 3 correspond to T0
through T3, respectively. Use 20-k
and AWG 22 to 28 lead wires. The connector has sol-
derless terminals and must be wired as shown below.
