HONEYWELL WEB-600E-O network controller

Description

The R7140 provides a pre-purge timing selectable from two
seconds to 30 minutes with power applied and the R7140
operating control indicating a call for heat:
a. Running Interlocks, Pre-Ignition Interlocks, Burner
Switch, Run/Test Switch, Lockout Interlocks and all
microcomputer monitored circuits must be in the
correct operating state.
b. The blower motor output, terminal 8, is powered to
start the PREPURGE sequence. The PREPURGE
timing for the R7140L does not begin until the High
Fire Switch is closed.
NOTE: A jumpered High Fire Switch adds a 30-second
hold before the purge time starts.
c. The Pre-Ignition Interlock input must remain closed
throughout PREPURGE; otherwise, control returns to
the STANDBY state and holds (30 seconds) for the
R7140G,M or safety shutdown for the R7140L occurs.
d. The Lockout Interlock or Running Interlock inputs
(interlock circuit including Airflow Switch) must close
by ten seconds into PREPURGE; otherwise, a
recycle to the beginning of PREPURGE for the
R7140G,M will happen or a safety shutdown for the
R7140L occurs.
e. When PREPURGE timing is complete, the firing rate
motor drives to the low fire position. If a damper
motor is used (R7140M), jumpers J1 and J2 should
be removed from R7140 subbase.
f. When the firing rate motor reaches low fire position,
the Low Fire Switch, terminal 13, is energized to
enter the Ignition Trial state.
