Operating Procedures for Timer Function
When Output Mode Z Is Selected
Present Value and Set Value
These items are displayed when the power is turned ON. The present
value is displayed in the main display and the set value is displayed
in the sub-display.
The values displayed will be determined by the settings made for the
time range and the timer mode in function setting mode.
Present Value and ON Duty Ratio (Output Mode = Z)
The present value is displayed in the main display and the ON duty
ratio is displayed in the sub-display. Set the ON duty ratio used in ON/
OFF-duty-adjustable flicker mode (Z) as a percentage.
ON duty ratio (%)
ON time = Cycle time x
The output accuracy will vary with the time range, even if the ON duty
ratio setting is the same. Therefore, if fine output time adjustment is
required, it is recommended that the time range for the cycle time is
set as small as possible.
Examples: 1. When Time Range = - - - - s (9999 s)
31(%)
20(s) x
100
Rounded off to the nearest integer (because of the
time range setting) → ON time = 6 s
2. When Time Range = - -. - - s (99.99 s)
31(%)
20.00(s) x
100
Rounded off to 2 decimal places (because of the time
range setting) → ON time = 6.20 s
If a cycle time is set, cyclic control can be performed in ON/OFF-duty-
adjustable flicker mode simply by changing the ON duty ratio.
Present Value and Cycle Time (Output Mode = Z)
The present value is displayed in the main display and the cycle time
is displayed in the sub-display. Set the cycle time.
Set each digit for the output time using the corresponding
