Overview
Output Error
Error is caused by:
• o ne or both outputs being shorted to a
• by shorting OSSD 1 to OSSD 2, or
• by an overload (greater than 0.5A).
Reset Input Error
This error occurs when the Reset switch
is closed (or the wiring is shorted to
+24V) during power-up.
EDM Input Error
Can occur for the following reasons:
• E DM wiring configuration does not
• No connection to EDM connections.
• Both EDM inputs fail to respond within
• Excessive noise on EDM inputs.
• Loose QD connection(s).
Receiver Error
This error can occur due to either
excessive electrical noise or an internal
failure.
DIP Switch Error
This error can be caused by incorrect
DIP switch settings or by changes to the
DIP switch settings when the system
is ON.
EDM 1 Error
This error can occur due to EDM 1 input
signal failing to respond within 250 ms
of the OSSDs changing state (ON to
OFF).
