RESET
In the event of a lockout condition, the M4RT1 can be reset via a minimum one second power inter-
ruption to terminal 7.
RESET OPTIONS (Special Order)
1.
Optional M4RT1 reset push button. When this optional reset pushbutton is installed, the M4RT1
can be reset by depressing this button for a minimum of one second.
2.
Remote reset option. With this option, the M4RT1 is provided with two additional screw termi-
nals. Using those terminals, a remote, dry contact pushbutton switch can be connected. The
maximum wire length is 100 feet (no.18 AWG wire size is recommended).
CAUTION: Remote reset is recommended only on a control solely for proved ignition pro-
gramming (pilot ignited burner) or a control for use only with appliances in which unburned
fuel cannot accumulate and that is intended for installation in inaccessible locations such as
open-flame, ceiling-suspended gas heaters.
WARNING: Selection of the Purge time and Recycle / Non-Recycle operation for a particular
application, by changes to the factory default jumpers described below, should only be per-
formed by a competent professional, licensed by a state or other government agency. Inap-
propriate selection of these safety critical parameters could result in an unsafe condition
hazardous to life and property.
PROGRAMMER JUMPER SETTINGS
The M4RT1 has a series of 8 jumpers that are used to configure the Purge timing, Pilot Trial for Igni-
tion (PTFI) timing, and recycle or non-recycle operation.
Purge Timing
Jumpers JP1 through JP5 are used to select the Purge timing for the M4RT1. The available Purge
timing selections are 5, 7, 30, 60, and 240 seconds and any additive combination of those times.
Selecting two or more Purge timing jumpers will result in a Purge time period equal to the sum of the
jumpers selected. Selection of a Purge time is accomplished by cutting or not installing the associ-
ated jumper. The factory set, default Purge time of 5 seconds (JP1 not installed) is always selected.
The Table below lists all available Purge times and how to select those by cutting jumpers JP2
through JP5.
