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.

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.
왘 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.
왘 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.
