Nor-Cal SDC15 Controller - Manual (Page 84)

■ Event channel def.
When the operation type is the timer start/stop, a target Event channel can be set.
• When the operation type of the same internal contact No. is set at “Timer
stop/start”, the display and setting can be made.
■ Input bit function
Four kinds of input bit functions are provided. What function of four functions is
used or is not used can be set.
• When the set value is “0”, the input bit function is not used and the default input
is used. The following shows the default input of each internal contact:
Internal Contact 1: DI (digital input) 1
Internal Contact 2: DI (digital input) 2
Internal Contact 3: OFF status
• In the input bit function, the logical operations (AND, OR) of each of internal
contacts 1 to 3 are combined. In input bit functions 1 to 4, the combination of the
logical operations may vary. The following shows one logical operation:
Logical AND Logical OR
OFF and OFF = OFF OFF or OFF = OFF
ON and OFF = OFF ON or OFF = ON
ON and ON = ON ON or ON = ON
• “OFF” is “contact open (OPEN)” or “0” when expressed using the numerical
value.
• “ON” is “contact close (CLOSE)” or “1” when expressed using the numerical
value.
