Direct (internal) feedback feature
All pumps with back- mounted SSV divider block have
the capability to feed back unused lubricant internally from
closed outlets directly to the reservoir (see R fig. 1, 4).
This procedure will start automatically, if outlet port 2 is
plugged with a closure plug. All pumps have capability to
feed back the lubricant directly to the reservoir from even
and odd outlets via the channel from outlet 1 to outlet 2 .
Start from the smallest outlet number when closing the
outlets, for instance 2, 4, 6 on even side or 1, 3, 5 on odd
side plus outlet 2. In fig. 4 the quantities of outlets 1, 2 and
4 (3xR) are fed back to the reservoir.
The remaining outlets are to be used for the connection to
the lube point or for increasing the lubricant quantity (dou-
ble or triple), see fig.1.
1013A94
CAUTION!
To change the outlet 2 for bearing lubri-
cation, replace closure plug with check
valve (Fig. 3), then never close outlet
(see page 7, fig. 1, pos. 1).
6001a02
NOTE
To feed back unneeded lubricant quanti-
ties from bottom- mounted divider
blocks to the reservoir, connect un-
needed outlet via the feedline to plug 5
(page 13, fig. 15, 16) for external return
line.

Operation
Pump
4205b03
Fig. 17 QLS 401 unit
The QLS 401 operates according to lube cycles (pause
and operating times).
With standard setting the pause time begins the cycle,
then the operating time occurs.
This can be changed by reprogramming the start stage
(see page 27).
A division of the lube points (option) via sub-divider
blocks and one main divider block (SSV 6, SSV 8) is
possible only up to max. 18 points per cycle. In this
case, the number of the cycles of the main divider block
must be set (see P3 on page 24).

Pressure Relief Valve
4304a00
Fig. 18 Pressure relief valve (cartridge) in housing
The QLS 401 is protected with a pressure relief valve
(cartridge).
The pressure relief valve limits the pressure build-up in
the QLS 401. It opens at an overpressure of 205 bar
(3000 psi).
If the pressure relief valve is actuated, this indicates that
the system is malfunctioning. The lubricant flows back
into the reservoir (hardly visible).
Upon expiration of the monitoring time of 15 minutes
(VAC models) or 25 minutes (VDC models), the pump
switches off. The fault indication ”Er” is displayed on the
keypad of the pump. See ”Display mode” under ”Control
unit”.

Pump ”running” is indicated on the display by a rotating
light movement of the green display (operating time).
If the voltage supply is interrupted during the operating
time, the times already expired are stored. When the
power supply is switched on again, the operating time
continues operating from the point where it had been
interrupted.

If the cycle is not complete within 15 minutes (monitoring
time) after expiration of the pause time, the pump
immediately switches off.
The fault indication ” Er ” (error) is displayed as a flashing
light (see page 12, fig. 14, pos. 1). At the same time, a
potential free contact is available for the external fault
indication (option), either as malfunction or as “Reservoir
empty”.

IMPORTANT
If a malfunction is present, the pump no
longer switches on automatically.
Acknowledge the malfunction (pos. 3). The flashing dis-
play changes into permanent light.
Only in this case, switch on the pump by pressing the
button for additional lube cycle (pos. 2).
When a malfunction is present, it can only be cancelled by
initiating an additional lube cycle and if a proper lube cycle
has been executed afterward.
If the fault is still present after an additional lube cycle has
been initiated, the fault indication ”Er” is displayed again.
The monitoring time starts at the same time as the operat-
ing time. It is a fixed time of 15 minutes.
If the voltage supply is interrupted during the monitoring
phase (operating time), the monitoring time starts from the
beginning after the pump is switched on again.
