RELAY CONTROL
The EMR4 must be in Preset Mode to control the flow valve solenoid(s). For a single-stage flow valve, use Relay 2
(Stop), for a dual-stage flow valve, use Relay 1 (Slow) and Relay 2 (Stop).
NOTE: Pushing the FINISH button at any time will cause a manual override condition and both relays will open.
When the relays open, both solenoids close, halting fuel flow.
Figure 15 illustrates Relay Control setup in Setup Mode.

NOTE:
See EMR4 Installation Guide, 577013-758 for Relay 1 (Slow) and Relay 2 (Stop) wiring connections to flow valve
Solenoid 1 (Fast Flow) and Solenoid 2 (Stop).

Note: This entry sets the number of volume
units prior to the finish of a preset delivery,
at which point, Relay 1 (Slow) will open,
causing the fast flow solenoid of a dual-stage
flow valve to close, halting flow. Recommended
setting is 5 volume units.
Note: Flow control relays are located
in the IB box. Each Display Head (1 or 2)
has two relays assigned to it. Installations
with only a
single-stage flow valve use
RELAY 2 (Stop).
Note: This entry sets the number of volume
units prior to the finish of a preset delivery,
at which point, Relay 2 (Stop) will open,
causing the single-stage flow valve solenoid
to close, or the stop solenoid of a dual-stage
flow valve to close, halting flow.
Recommended setting is 0.1 volume units.
