Explanation of Functions
Operating Procedures for Twin Timer Function
OFF Time Range (oftr)
Set the time range for the OFF time
in the range 0.001 s to 999,999 h.
ON Time Range (ontr)
Set the time range for the ON time
in the range 0.001 s to 999,999 h.
Timer Mode (timm)
Set either the elapsed time (UP) or remaining time (DOWN) mode.
In UP mode, the elapsed time is displayed, and in DOWN mode, the
remaining time is displayed.
ON/OFF Start Mode (totm)
Set the output mode.
Set either flicker OFF start or flicker ON start.
(For details on output mode operation, refer to Timing Charts on page
31.)
Input Signal Width (iflt)
Set the minimum signal input width (20 ms or 1 ms) for signal, reset,
and gate inputs.
The same setting is used for all external inputs (signal, reset, and gate
inputs).
If contacts are used for the input signal, set the input signal width to
20 ms.
Processing to eliminate chattering is performed for this setting.
NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format.
Set an NPN input when using a two-wire sensor. The same setting is
used for all external inputs.
For details on input connections, refer to page 10.
Instantaneous/Time-limit (otmd)
Set the contact output to time-limit SPDT + instantaneous SPDT or time-
limit DPDT operation.
Set Value Upper Limit 1, 2 (sl1hH and sl2h)
Set the upper limit for the set value when it is set in run mode.
The limit can be set to between 1 and 999999.
Key Protect Level (kypt)
Set the key protect level.
Refer to Key Protect Level on page 38.
Output inversion (ot-i, ot1i, ot2i)
Set logical inversion of output ON/OFF. In the case of two outputs, it
is possible to individually set output inversion for each of output 1 and
output 2 (OUT1 and OUT2). If output inversion is n-o (Normally
Open), the output turns ON when the set value is reached. If output
inversion is n-c (Normally close), the output turns OFF when the set
value is reached.
Indicator Display Mode (indc)
Settings can be made to display the present value in status indicator.
When this mode is ON, the status indicator changes in accordance
with the ratio of the present value to the set value. In the case of
ALOF, the indicator display is turned OFF, and the status indicator is
all off. In the case of ALLT, the indicator display is turned OFF, and
the status indicator is all lit.
(Example 1) When incrementing input is performed
The status indicators light up in an order starting from the left, when
the status reaches 1/6, 2/6, 3/6 (50%), 4/6, 5/6, 6/6 (100%) in
accordance with the ratio of the present value to the set value. Three
indicators on the left light up when the status reaches 50%, and all
indicators light up when the status reaches 100%. All indicators are lit
even when the status is 100% or more. All indicators turn off when the
value changes from 999999 to 0. If the timer continues thereafter, the
status indicator will light up according to the present value.
(Example 2) When decrementing input is performed
The status indicators turn off in an order starting from the right, when the
status reaches 5/6, 4/6, 3/6 (50%), 2/6, 1/6, 0 in accordance with the ratio
of the present value to the set value. Three indicators on the right turn off
when the status reaches 50%, and all indicators turn off when the status
reaches 0.
Output ON Count Alarm Set Value (on-a, on1a, on2a)
Set the alarm value for the output ON count.
The limit can be set between 0×1000 (0 times) and 9999×1000
(9,999,000 times). Only the underlined values are set. The alarm will
be disabled if 0 is set.
100,000 times is set in the default settings.
If the total output ON count reaches the alarm set value or above, an
RPLC (replacement time) error can be displayed on the Timer.
For details, refer to page 37.
Output ON Count Monitor Value (on-c)
The monitor value is only displayed. It cannot be set.
The output ON count will be 1,000 times the displayed value.
ON Count Monitor Values for Outputs 1 and 2 (OUT1 and
OUT2) (on1c and on2c)
The monitor value for output 1 and 2 (OUT1 and OUT2) is only
displayed. It cannot be set.
The output ON count will be 1,000 times the displayed value.
Cumulative Run Time Alarm Set Value (ot-a)
The cumulative run time for notifying the replacement time can be set.
For details, refer to page 37.
Cumulative Run Time Monitor (ot-c)
The cumulative run time is displayed. It is not a setting item. The
numerical values are displayed in increments of 0.1 years.
