Counter under reset does not operate ad its output is turned OFF

. Reset signal input during re-monitor input restores reset count (timing) value of the specified Counter While reset signal is ON, RST indicator lights.

Reset count (timing) value of specified Counter can be re-monitored, and restored by reset input. While re-monitor signal is ON, RCV indicator lights.

Nomenclature

I/O Inhibit Indicator

Indicates that the input/output inhibit input signal is ON.

Re-monitor Input Indicator

Indicates that the re-monitor input signal is ON.

Reset Input Indicator

Indicates that the reset input signal is ON.

Counter No. Indicator

Indicates the number of the Counter whose data (count value, preset value, etc.) is currently displayed.

RESET Key

Resets the count value and output signals.

COUNTER No. Key

Selects the Counter in sequence each time this Selector is pressed: (Any Counter whose forecast value is set to 0 is skipped in the RUN mode.)

RUN

The following indicators light to show that the count value has reached the preset value and that the output has turned OFF.

Count Value

Indicates the current count (current time in timer mode)

Set Mode Indication

Preset Value

Always indicates the forecast value during the RUN operation. Indicates the set value in each setting mode.

Up Keys 1 to 6

Each of these keys increments the preset value of the corresponding digit, each time it is pressed.
