2.4. Operating Conditions
Maximum liquid temperature: 35°C, short term up to
60°C.
Density of pumped liquid: max. 1100 kg/m
Ph-value of pumped liquid: 5 up to 11.
Operation: The motors are designed for continuous
operation (S1) with fully submerged motor, maximum 15
starts per hour.
Sekamatik 100 E S unit is designed for 40% S3 intermittent
operation.
Our standard warranty and maintenance regulations refer to
intermittent operation. For reduced warranty periods and
service intervals due to continuous operating conditions
please contact our service department.

2.5. Explosive Environments

For operation of the pumps in explosive environments
only models with explosion-proof motors (Ex model) must be
used.
For each individual installation the explosion
classification (Ex-class) of the pump must be approved by
the local authorities.
3. Warranty
Our warranty only covers pumps which are installed and
operated in accordance with these installation and operation
instructions and accepted codes of good practice and being
used for the applications mentioned in these instructions.

4. Transport and Storage

Never use the cable, the pump or the pressure
compensation hose to lift, lower or transport the unit.
The unit may be transported and stored in vertical or
horizontal position. Make sure that it cannot roll or fall over.
For longer periods of storage, the unit should be protected
against moisture, frost or heat.

5. Electrical Connection

5.1. General instructions

Before operation, an expert check must secure that the
required electrical protection measures exist. The
connection to ground, earthing, isolating transformer, fault
current breaker or fault voltags circuit must correspond to
the guidelines set forth by the responsible power plant.
The voltage required in the technical data sheet
must correspond to the existing line voltage.
Make sure that the electrical pin-and-socket connections
are installed flood- and moisture-safe. Before starting
operation check the cable and the plug against damages.
The end of the pump power supply cable must not be
submerged in order to prevent water from penetrating
through the cable into the motor.

The normal separate motor starter/control box of
standard as well as of explosion proof pumps must
not be installed in explosive enviroments.
The electrical connection of the pump should be carried out
in accordance with local requirements.
The operating voltage and frequency are marked on the
pump and controller nameplates. Voltage tolerance : +6% up
to -10% of the voltage stated on the nameplates. Make sure
that the lifting station is suitable for the electricity supply
available at the installation site.
The disposal units are supplied with a control box. Controller
for single-phase pumps also incorporates the operating
capacitors required.
The pump motors have a thermal switch incorporated in the
motor windings. The thermal switch protects the motor from
overheating by cutting off the supply to the pump via the
controller.
The electrical connection must be carried out in accordance
with the marking on the cable to the controller.
The lifting stations require no additional motor protection.
Connect the units to the mains supply.
An external fault signal device can be connected to the
controller via the potential-free fault signal output. Maximum
load : AC 250 V, 5 A, AC 1.
Motor-Start
The motor of units are designed for direct-on-line (DOL)
start.

5.2. Electronic control box

The equipped electronic control box controls the operation
functions and announces failures which may be occure.
5.2.1. SEKAMATIK 100 E single station
The function selector offers the following functions:
Operation switch
Position "Manu"
The pump operates, irrespective of the liquid level in the
tank. To stop the pump release the switch. The switch turns
into the position "Aus/Off".
Position "Off/Reset"
The pump is stopped.
Position "Auto"
Pump operation according to the liquid level in the tank.
Switch "Reset"
This switch is used to quit a failure before re-starting the
unit.
Acoustic alarm switch
Position "On"
The built-in acoustic alarm is activated. Together with the
red LEDs "Alarm"and "Failure" the built-in acoustic alarm will
start if the level of the medium is above the alarm level. The
alarm is automatically reset when the liquid level has been
lowered below the alarm level.
Position "Off"
The built-in acoustic alarm is not activated.
The controller front cover features Light-Emitting Diodes
(LEDs) for indication of operating conditions :
Yellow or red LED "Incorrect phase sequence" (only 3-
ph models)
The yellow LED in the front cover of three-phase controllers
