Setting the special utility relay
The special utility relay must be set to output the clock pulse. Set the relays in the
following manner.
•
Only one relay for each group can be turned ON from relays 2104 through 2107
and 2108 through 2111.
•
Use the SET-RES pair or STA instruction to turn relays 2103 through 2112 ON/
OFF.
•
Turning OFF relays 2104 or 2108 enables control of output relay 0500.
•
To change the pulse width, be sure to first turn ON relays 2103 or 2112 to auto-
matically clear the current value of CTH0. You cannot change the pulse period
unless you turn ON relays 2103 or 2112.
•
Turning ON/OFF relay 2105 stops/outputs the clock pulse.
Note: If two or more relays of special utility relays 2104 through 2107 or 2108
through 2111 are turned ON, priority is given to the relay with the smaller number.
Operation of output 0500 by setting special utility relays
Outputting a pulse with 1:1 ON/OFF ratio
Outputting a pulse with variable pulse width
