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 func-
tion 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. "SET1" lights at the same time.
Set the ON duty ratio used in ON/OFF-duty adjustable flicker mode
(Z) as a percentage.
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.
ON time = Cycle time × ON duty ratio (%)
The output accuracy will vary with the time range, even if the ON
duty ratio setting is the same. Therefore, if fine output time adjust-
ment is required, it is recommended that the time range for the cycle
time is set as small as possible.
Examples:
1. If the cycle time is 20 s, the ON duty ratio is 31%, and the time
range is 1 s to 9999 s, the ON time is given by the following:
31 (%)
20 (s) ´ = 6.2 (s) ® Rounded off to the nearest integer
100
(because of the time range setting) ® ON time = 6 s
2. If the cycle time is 20.00 s, the ON duty ratio is 31%, and the time
range is 0.01 s to 99.99 s, the ON time is given by the following:
31 (%)
20.00 (s) ´ = 6.200 (s) ® Rounded off to 2 decimal places
100
(because of the time range setting) ® ON time = 6.20 s
