GUIDELINE ON VALVE INSTALLATION
In the case of suction problems during installation, place the valves on a firm surface and tap the
PTFE ball seat disk lightly with a brass rod and a hammer weighing about 300 g. Let the valves
operate in the wet state.

S2Ba/S2Ca-019-D
NOTE
If suction problems with the pump or leakage at the overcurrent valve are encountered,
first clean the ball and the ball seat disc.
For media containing particles larger than 0.3 mm it is absolutely essential to install a
filter in the suction line.
5 Features of the S2Ca metering pumps
5.1 Function description, motors
The pump has an integrated electronic overload cut-out in all versions. This responds as soon as
the maximum admissible power consumption is reached and stops the motor.
If the motor stops due to a system overload the electronic controller detects the fault and
transmits a message which is displayed on the display panel and at the pump.
The fault signal can be cancelled by pressing the P key, altering the level for a brief period at
the pause input (switch function) or by reconnecting the pump to the mains.
IMPORTANT
If the motor has been switched off via the electronic overload cut-out, check that the pump
is not continuously overloaded.
