5.4 Advanced TVFD Valve Settings
5.4.1 Hardware
• TVFD (SUV) Solenoid Upper Valve (V12)
• TVFD (SLV) Solenoid Lower Valve (V11)
• TVFD Upper Position Sensor (UPS) monitoring slide valve (V12)
• TVFD Lower Position Sensor (LPS) monitoring slide valve (V11)
5.4.2 PLC Settings
1 Presep (Softkey) = Off (standard setting)
2 AEB-TVFD (Softkey) =Off (standard setting=On)
3 TVFDAdv (Softkey) = On (standard setting= Off)
If TVFDAdv is activated (Switch = On), TVFDAdv overrides 1 and 2 above.
5.4.3 Timer settings
LSOTmr (Bin Emptying Time)
T = Timer sets the Open time (Emptying time) lower slide valve. Default 10 second
TVFDC-Al
T = sets the maximum time that you can accept it will take to perform the slide valve closing sequences of the
upper and lower slide. The default setting is 15 seconds. If the slide valves do not perform this sequence within
the set time, the unit goes into Off mode.
TVFDO-Al
T = sets the maximum time that you can accept it will take to perform the slide valve opening sequences of the
upper and lower slide. The default setting is 15 seconds. If the slide valves do not perform this sequence within
the set time, the unit goes into Off mode.
5.5 Rotary valve settings
5.5.1 Hardware
• The rotary valve is started by a 24VDC signal
• Rotation detection device (optional), e.g. inductive proximity sensor
• Fault signal from rotary valve (optional) (active high)
• Level indicator (optional)
5.5.2 PLC settings
Rot valve:
Enab = ON
Dete = ON (if rotation detection installed)
Trun = Duration for which the rotary valve runs
T1 = Duration between rotary valve operations
Err = ON (if fault detection is installed)
Rot valve LI:
T2 = Period after the level indicator indicates before a rotary valve operation begins
R_LI = ON (if rotary valve level indicator is installed)
Rot fault:
T = Time before a rotary valve fault triggers an alarm
Auto empt. (softkey) = ON (enables periodic rotary valve operation)
