Installation
Installing the Lubrication Controller
CAUTION
This Lubrication Controller is not designed to be
operated in a caustic environment.
1.
Select a flat surface upon which to install the
Lubrication Controller, and drill mounting holes
according to the Mounting Hole Layout on
page 10.
CAUTION
Use only the pre–drilled holes under the cover fas-
teners to mount the timer. Failure to use the desig-
nated mounting holes could cause circuit board
damage.
2.
Remove Lubrication Controller cover, and secure
the junction box using four #6 screws (not pro-
vided).
CAUTION
Do not ground any lead for the pressure switch or
the low level switch. Circuit board damage may
result.
3.
Connect solenoid valve leads to terminals 4(–) and
6(+) (output).
4.
Fig. 2. Step optional for use of external alarm.
Terminals 7 and 8 are a normally open, voltage-
free switch, available as a switching device for an
external alarm circuit. Connect fused (+) power
supply (not supplied) to terminal 8. Connect termi-
nal 7 to external alarm. Ground external alarm to
complete circuit

5.
This step is optional.
Connect terminals 9 and 11 to a normally-open
pressure switch installed in system lubricant
supply line for pressure-controlled system shut-
down.
NOTE: The pressure switch, upon detecting the
preset pressure, will send a signal to the Lubrica-
tion Controller to deactivate the air solenoid valve,
which will deactivate the pump.
6.
This step is optional.
Connect terminals 12 and 13 to a normally-open
low-level switch (user provided).
NOTE: Upon detection by a low-level sensor, the
Lubrication Controller will activate the alarm condi-
tion.
CAUTION
If using the low level indication feature, the lubrica-
tion controller will remain in alarm mode and will not
function until the low level switch is opened by refil-
ling of the fluid reservoir. Failure to correct the low
level condition will result in interruption of the auto-
matic lube system which could lead to premature
bearing failure.
7.
This step is optional.
Connect terminals 14 and 15 to a normally open
switch. Closing of the switch will suspend Lubrica-
tion Controller operation. Reopening of the switch
will resume Lubrication Controller function from the
point at which operation was suspended.
WARNING
AUTOMATIC SYSTEM ACTIVATION
Do not connect power to timer if the pump
power supply is on, unless activation of the
automatic lubrication system is intended.
This device is an automatic timing device
that activates the output circuit (air
solenoid valve) upon power connection or
upon exit of the programming function.
Ignoring this warning could lead to serious injury
including fluid injection and amputation due to
activation of connected system components.
8.
Connect the power leads from an isolated power
supply. Connect terminal 3 to the negative (–) lead
(ground), and connect terminal 2 to the positive (+)
lead.
9.
Replace the Lubrication Controller cover.
