Installation and Operation Instructions
Description of QLS 311
The QLS 311 is a complete compact lubrication system
for
a maximum of 18 lubrication points per cycle*
.
*Note: More than 18 lubrication points are possible for
applications with limited lubrication requirements. Contact
Lincoln Industrial Technical Sevice for additional informati-
on.
The pump has three basic configurations:
- SSV divider block mounted on the back (see fig. 15)
- SSV divider block mounted on the bottom (see fig. 16)
- Pump without the SSV divider block attached.
The pump with the SSV divider block mounted on the
bottom has the capability of using steel tubing as
lubrication lines if necessary.
Standard lubrication lines are high pressure plastic
tubing included in the pump installation kit for pumps with
the SSV divider block attached.
Note: Regardless of the SSV divider mounting the operation
of the pump is the same.
A signal from the pump timer starts the electric motor and
the pumping element starts pumping the lubricant to the
SSV divider block.
When all lubrication points have received lubricant, an
internal proximity switch turns the motor off, completing
one lubrication cycle.
If pump does not complete the cycle within 15 minutes of
operation, an alarm message
Er
will be displayed as a
flashing light in the keypad window.

Operation of QLS 311
Fig. 16 - QLS 311 with bottom mounted SSV divider block
The QLS 311 operates according to lube cycles (pause
and operating times).
The pause time begins the cycle, then the operating time
occurs.
A division of the lube points
(option)
via secondary
metering devices and one main divider block (SSV 6,
SSV 8) is possible only up to
a maximum of 18 points
per cycle
(see * Note). In this case, the number of the
cycles of the main divider block must be set (see P 3 on
page 14).
