4.8 Time signal output
At starting each step, the time signals 1 to 4 are turned on upon elapse of the time set on the ON delay timer.
Then, the output is turned off upon elapse of the time set on the OFF delay timer.
During the time signal output ON, corresponding lamps of TS1 to TS4 light up.
Select the function selection among 0 to 5 of TS 1 to 4 at each step; if either one of 1 to 4 is selected, the above
operation is performed with the setting; if 0 is selected, no function is available; if 5 is selected, ON is always set
during the selection step.
If the time is set backward by using the  or  key, even after elapse of time, the output returns to the one
corresponding to the point at which the time set backward and time counting starts at that point, i.e., in the middle
of the way.
Example: If the elapsed time is returned by 5 minutes by using the  key 3 minutes after the OFF delay
terminates, the output turns on and the OFF delay counts for 2 minutes.

4.9 Time output
During a program run, the Time output is always ON as in-a-run signal output.

In-a-run signal output/end signal output selection function
The use purpose of one relay output is selected from either in-a-run signal output or end signal output.
4.10.1 When selecting the in-a-run signal output
During a run, the relay output is always ON as in-a-run signal output.
4.10.2 When selecting the end signal output
At termination of the program run, the output as the end signal output is turned on or off according to the
following flow.
If the setting is above the maximum value within the setting range (“~~~~~” to be displayed), the output remains
turned on until the reset status described in Section 5.3.1 is established.
Also, the END lamp lights up.

4.11 DI (external input)
Operation including run can be performed via DI through the external drive signal selection.
For the function of each DI, see Sections 4.10.1 to 4.10.4.
No operation is performed for [external drive signal = OFF].
4.11.1 Run/reset DI
The following operation is performed when ON continues for 2 seconds after the external contact open (OFF)
changes to the external contact closed (ON):
During a run: The run stops.
During a stop: A run starts.
4.11.2 Hold DI
The following operation is performed when ON continues for 2 seconds after the external contact open (OFF)
changes to the external contact closed (ON):
During a run: The run stops momentarily.
During a momentary stop: The run restarts.
