External Input Signal
The PL unit’s RAS interface connector uses the following input signals.
Standard Signal Input (DIN)
This standard digital input is used for alarm detection in external devices. The input
signal uses two bits.
The System Monitor utility can be used to enable or disable this feature, as well as
designate what type of processing is to be performed once a signal is received.
Remote Reset Input
This is the reset signal sent from an external device to the PL. When this signal is en-
abled, a forced reset of the PL is performed.
The System Monitor utility can be used to enable or disable this feature
• General Purpose Input (DIN) level must be 1.5S or longer to be de-
tected.
• Be sure the voltage value between terminals is controlled via the in-
put voltage, so that the PL is operated within its recommended range.
If the input voltage exceeds this range, a malfunction or PL damage
may occur.
• With Sink/Source input, even if the D(-), and RESET(-) are positive,
and D(+), RESET(+) are negative, no problems are created. Be sure to
operate the unit within the recommended voltage range.
