Intended Use
Model V340HH electronic air shutoff
assembly is designed to operate exclusively
with Lincoln PMV pumps
The function of the electronic air shutoff
assembly, also known as an overrun con-
troller, is to prevent pump damage, due to
high runaway speeds (excessive number of
pump cycles per minute), if lubrication drum
or tank is emptied.
The overrun controller will shut off the
pump, and signal an alarm if the pump
exceeds its pre-set cycle rate.
Any other use not in accordance with
instruction will result in loss of claims for
warranty and liability.
System Overview
The electronic air shutoff assembly operates
as a pump speed monitor and overrun
controller for instances where pump speed
exceeds preset levels due to low lubricant
levels.
Pump cycles are continuously monitored
by a Programmable Control Board (PCB) for
correct operating cycles. If the pump cycles
exceed PCB settings, a solenoid is activated
which utilizes compressed air to shutoff
pump operation.

Description
The electronic air shutoff assembly monitors
pump speed as the overrun controller
assembly receives a discharge of
compressed air from the pump with each
pump cycle.
A processor detects air discharges via a
pressure switch. If the CPM (Cycles Per Min-
ute) exceeds a preset number of cycles, a
solenoid is activated which redirects the dis-
charged air, which in turn activates a mech-
anism which interrupts pump operation.
For specifications, refer to Table 1.
For a listing of controls and indicators,
refer to Table 2.

Remote Monitoring
The option is available to connect the elec-
tronic air shutoff assembly to a remote
monitoring device such as a Programmable
Logic Controller (PLC).
Referring to fig. 5, page 6, a two-part
DIN connector is attached to the PCB hous-
ing of the electronic air shutoff assembly.
The socket half of the DIN connector can

• To manually stop pump activity and
overrun controller, press TEST (22).
• To restart pump activity, press TEST (22).
• If the battery life drops below 25%, red
LED light (18) will blink. To check this or
any error, press B (21).
Run mode
Refer to table 3 for run mode options.
• Once overrun controller is properly
installed, press A (20) († fig. 5) to start
pump.
• When pump is running without any
errors, green LED light (19) blinks
continuously.
• If no key is pressed for more than
30 seconds after pump starts,
overrun controller goes into standby
mode and turns display (17) off to
conserve battery life. Pump and overrun
controller continue functioning while in
standby mode.
• To turn display (17) on while in standby
mode, press A (20).
1 Holding TEST (22), press B (21) + A (20)
+ B (21) within 5 seconds († fig. 5). Do
not release TEST (22).
2 Continuing to hold TEST (22), adjust cy-
cles/minute value by pressing A (20). Each
key press will reduce the cycles/minute
value by 5 units.
3 Release TEST (22) and hold B (21) until
display (17) blinks. This indicates the cy-
cles/minute value has been stored. Unit
then automatically initiates run mode.
Setting cycles per minute
Do the following to modify the cycles/minute
setting:
4 Holding TEST (22), press B (21) + A (20)
+ B (21) within 5 seconds († fig. 5). Re-
lease TEST (22).
5 Adjust cycles/minute value by pressing A
(20). Each key press will reduce the cy-
cles/minute value by 5 units.
6 To store the cycles/minute setting, hold B
(21) until display (17) blinks. Unit then
automatically returns to run mode.

• Hold A (20) for 5 seconds to reset overrun
error condition († fig. 5, pg. 6).
Sleep mode
The overrun controller enters sleep mode
when it does not receive any pressure switch
signals for more than 30 seconds.
Green LED light (19) will also stop blink-
ing, indicating that overrun controller is not
receiving any signals from pressure switch
(pump is not running) († fig. 5, pg. 6).
When the pressure switch signal resumes
(pump resumes activity), the overrun con-
troller will re-enter run mode.
Error codes
Red LED light (18) († fig. 5, pg. 6) will blink
when error conditions are detected. During
error conditions, the pump will stop. Refer to
table 6 for error code functions.
To view the error code on the digital display
(17), press B (21).
00 – No error
01 – Low battery
02 – Cycles/minute overrun
03 – Low battery and cycles/minute
overrun
0C – Solenoid error (on power-up only)
!Notice
To exit setup mode without saving
any changes, do not press any buttons
for 30 seconds.
!Notice
Setting cycles/minute value to 00
places unit in bypass mode, disabling
unit from monitoring cycle activity and
responding to overrun events.
