Relay Operation
1.
Drive Inhibit Relay
A NO relay is used to inhibit the operation of equipment. Operators must log into the
display first before the relay closes which allows the equipment to be used.
When the key is turned to Off, the relay will open back up and the equipment cannot be
used until another operator has logged in.
2.
Auxiliary Relay
A NO relay is used for the auxiliary relay. The most common item connected to the
auxiliary relay is a strobe/alarm combo.
The relay will remain open until an exception occurs that exceeds the lockout threshold
and the display will lock out. Once the screen locks out, the relay will close and
depending on how it is wire, it will supply a ground signal to activate the strobe. See
section 8 below for more details on how to wire this up.
The relay will remain closed until the screen has been unlocked.
3.
Inputs
There are two inputs currently available on the Sapphire V2S. These can be used to detect
operating values/times of various functions.
Inputs do not affect the operation of the equipment. They are only a counter
to determine the time On or time Off.
