REMOTE FILE SELECTION
The InSight II scanners have four (A,B,C,D) programmable memory files. The user has the option of
storing different scanner setpoints for different operating conditions (e.g. Gas / Oil, Pilot / Main, Low Fire
/ High Fire, etc.) in these files. With RFS selected as “
Line Inputs
”, one or two external switches (sup-
plied by user) will select between the files when the RFS1 or RFS2 wires are connected to 24 vdc (-).
The default is
RFS = “Key Pad”
which allows manual file selection at the scanner keypad only. The
user may also select
RFS = “Comms”
which will allow manual selection at a remote computer running
Fireye software. Fireye recommends the use of shielded cable for the two remote file select switches (or
relays). The switch contacts should be rated for low current operation (3mA dc).
