REMOTE FILE SELECTION
The InSight Series 4 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
(supplied 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).
The InSight Series 4 can be programmed to automatically switch between file A and file B after a set
period of time ( RFS = “Flame Relay” ). This is described in detail in the menu section below. The
expected purpose is for flame scanner monitoring between the states of pilot flame on and main flame on
as they are sequenced by the burner control.
