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. Type: 100 – 230 V ± 10 %, 50/60 Hz at 100 V at 230 V nominal output 250 W 250 W nominal current 3.2 A 2.0 A peak current (in operation)* 10 A 5.5 A making peak current 12 A 24 A fuse, internal** 4.0 AT (1.5kA) 4.0 AT (1.5kA) * internal switching ** Only genuine ProMinent fuses, item no. 732414, may be used! 5.2 Function description, controller Operating modes Operating modes are selected using the MODE menu (depending upon identity code, some operating modes may be absent). “Analogue” 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. “Manual” operating mode: The stroke rate is controlled manually via the controller. “Contact” 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. “Batch” 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 preselected via the control unit. ProMinent® Page 33 Features of the S2Ca metering pumps Dulcodes UV-Desinfektionsanlage Functions Optional relay Function and error indicators LCD indicator LED indicator “PROFIBUS®” mode: (Identity code, control variant: PROFIBUS®) This operating mode provides the option of controlling the pump via the PROFIBUS® (see “Supplementary instructions for ProMinent® gamma/ L and ProMinent® Sigma versions with “PROFIBUS®”). The following functions can be selected using the SET menu: “Calibrate” function (Identcode, stroke length adjustment: manual + calibration): The S3Ca can be operated in all operating modes including in calibrating mode. The corresponding continuous displays can show the actual feed quantity or the feed rate. Calibration is maintained within the stroke frequency range 0-180 strokes/ min. Calibration is also maintained when a stroke frequency is altered up to ±10 % scale divisions. “Auxiliary frequency” function: It is possible to set a stroke rate in the SET menu, which may be activated via the “external control” terminal. This auxiliary frequency overrides all other pre-set stroke rate frequencies. “Flow” function: Stops the S2Ca when the flow is insufficient. In the SET menu, the number of failed strokes is entered after which the pump will be turned off. The following functions are available as standard: “Float switch” function: Information on the liquid level in the feed chemical container is transmitted to the S2Ca. This option requires the installation of a 2-stage float switch. This is connected to the “float switch” terminal. “Pause” function: The S2Ca can be stopped by remote control via the “external control” terminal. The “pause” function operates only via the “external control” terminal. The following functions are activated by keystrokes: “Stop” function: The S2Ca can be stopped by pressing the STOP/START key without disconnecting from the mains power supply. “Prime” function: Priming (short term feed at maximum frequency) is activated by pressing both arrow keys at the same time (in “Stroke rate” permanent display). The S2Ca has two connection options (not in PROFIBUS® version). Optional “fault-indicating relay” or “power relay”: In the event of fault signals, warning signals or float switch activation signals, connects an electrical circuit to trigger alarm sirens etc. Th...
