5.1Function 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.

NOTE

¥The motor is supplied pre-wired.

¥The performance data in 3.1.1 are measured with the S2Ba (base model with 3-phase motor). If the S2Ba has been fitted with a 1-phase motor there may be up to 5 % speed reduction due to the different motor characteristic curve, i.e. corresponding 5 % reduced feed rate.

¥The controller changes over to digital stroking mode at low stroke frequencies! This takes place at stroke frequencies below 1/3 of the maximum stroke frequency. This function is designed to ensure sufficient cooling of the motor and low stroke frequencies.

5.2Function description, controller

Operating modes Operating modes are selected using the MODE menu (depending upon identity code, some operating modes may be absent).

ÒAnalogueÓ operating mode: (Identity code, control variant: analogue)

The stroke rate is controlled via an analogue electrical signal via the “external control” terminal. Signal processing is pre-selected at the controller.

ÒManualÓ operating mode:

The stroke rate is controlled manually via the controller.

ÒContactÓ operating mode:

This operating mode offers the opportunity to make fine adjustments with small increase/ decrease factors. Dosing can be activated by a pulse via the “external control” terminal or by a semiconductor element. With the “pulse control” option it is possible to pre-set a feed quantity (batch) or number of strokes (factor 0.01 to 99.99) via the control unit.

ÒBatchÓ operating function:

This operating mode offers the option of working with larger transfer factors (up to 65535). Metering can be triggered by pressing the P key or a pulse from the “external control” terminal via a contact or semiconductor element. A batching quantity or number of strokes can be pre- selected via the control unit.
