Page 20: Pump And Pressure Control
Pump and pressure control General Oil output pressure is controlled by frequency converters FC1 (Pump 1) and FC2 (Pump 2). The oil output pressure transmitter (PT1) is connected in parallel with both frequency converters. Return oil temperature determines whether pumping is carried out in normal mode or cold start mode. The pressure control parameters which can be set through the user interface include the following: "... -
Page 21: Cold Start Mode
system starts the selected main pump and the Pump changed alarm is reset. Before taking the above action, the cause of the pump change must be determined and the problem cleared. Stopping and restarting pumping using the Pump on/off switch always starts the pump selected as the main pump. - Page 22 For example: TS3 high cold start temperature = 40 degrees TS3 low cold start temperature = 20 degrees Pressure setpoint = 5 bar Cold start pressure = 2 bar Pressure when return oil temperature is 30 °C = 3.5 bar Return oil at 40 °C cold start mode ends and system oil pressure is at setpoint 5 bar...
-
Page 23: Bypass Valve Control
Bypass valve control The system opens bypass valves only when the pump is started in cold start mode. When bypass valves are opened the oil circulation system oil flow is mainly circulated in the main lines, in general there is no oil flow going to the lubrication points. - Page 24 reservoir, stop level (LS2) alarm is generated. The status of the thermostat (TS1) is not shown in the main view. When heating is turned on and the thermostat is closed, H light is green.It goes grey, when the thermostat opens. Reset the alarms from the heating control switch.

Page 27: Alarm Types
Alarm types Pumping is off The pump on/off switch is in OFF position or an alarm was generated, stopping the pump. The cause of the alarm stopping the pump is also displayed in the scroll bar. Pump changed The system switches from one pump to another in circumstances described in the Automatic pump change chapter. -
Page 28: Frequency Converter 1 Fault (Fc1), Frequency Converter 2 Fault (Fc2)
The alarm is automatically reset once the flow meter is no longer in alarm mode. Flowmeter communication alarm The ST-2240-CIRC control centre and the Flowline monitor flowmeters communicate via the RS-232 serial bus or CAN bus. A flowmeter communication fault is generated when one of the flowmeter groups connected to the system no longer responds to the ST-2240-CIRC control. -
Page 29: Water Level (Ms)
Water level (MS) If a float switch for water sensing is connected in the system, the water alarm occurs when the float switch opens. The alarm is automatically reset once the switch is no longer open. Output oil temperature alarm Alarm occurs, if the output temperature of the oil is higher than the parameter Temperature alarm limit. -

Temperature alarm limit If the temperature of the output oil is higher than Temperature alarm limit, the temperature alarm is triggered. Cold start pressure If the return oil temperature (TS3) is below TS3 low cold start temperature, the system adjusts oil pressure to the value specified in the Cold start pressure parameter. - Page 38 Start alarm delay If pumping is started or an automatic pump change has taken place but oil pressure does not exceed the Pressure alarm limit parameter within the period specified in the Start alarm delay, a pressure alarm is generated and pumping will stop.
