With this function you can activate or deactivate the
digital input for thermal failure of pump 6
Deactivation of this input is only recommended in
combination with the use of a VFD per pump.
If this function is activated you must connect a
thermal failure signal of pump 6 or make a wire bridge
between the com of the digital inputs and TH.FAIL P6
input.
Input Par. 3-8-1-10
Function RDP
With this function you can activate or deactivate the
digital input for run-dry protection via a digital contact
e.g. Floater switch.
Deactivation of this input is only recommended in
combination with the use of another protection device
like a pressure transmitter on the suction side.If this
function is activated you must connect a run-dry
protection contact or make a wire bridge between the
com of the digital inputs and the RDP input.
Input Par. 3-8-1-11
Function TFR
With this function you can activate or deactivate the
digital input for the thermal failure of the VFD in the
configuration VFD changeover.
If this function is activated you must connect a
thermal failure signal from the VFD or make a wire
bridge between the com of the digital inputs and the
TFR input.
Input Par. 3-8-1-12
Function TVA
With this function you can activate or deactivate the
digital input for the thermal failure of the supply valve
in the configuration Level valve on/off.
If this function is activated you must connect a
thermal failure signal of the supply valve or make a
wire bridge between the com of the digital inputs and
the TVA input.
Input Par. 3-8-1-13
Function Off
With this function you can activate or deactivate the
digital input for the external off function.
If this function is activated you must connect an
external signal off or make a wire bridge between the
com of the digital inputs and the OFF input.
Input Par. 3-8-1-14
Function Fire
With this function you can activate or deactivate the
digital input for the external fire function.
If this function is activated you must connect an
external signal for fire alarm or make a wire bridge
between the com of the digital inputs and the FIRE
input.
9.8.4.1.2 Definable outputs Par. 3-8-2
Table 32: Special outputs
ATTENTION
Special outputs only available with the
6 pumps Megacontrol. They are only
available if the connection is not
occupied by a pump.
Output Par. 3-8-2-1/2/3/4/5/6 These digital outputs of
pump 4/5/6 are only available when no pump function
is selected to its output.
Function None:
No function is chosen the normal pump function is
active (see parameter 3-3-1 number of pumps)
Function Treshold relay 1:
The function threshold relay is only available when in
parameter 3-3-2 Inlet the function valve on/off or prop.
is chosen.
Only after choosing the function “threshold relay”, the
following parameters will be visible
Par. 3-4-1-4-8-1 Treshold 1 on
Par. 3-4-1-4-8-2 Treshold 1 off
With this configuration of the selected digital output
(P4/P6 and FR4/FR6) you have an extra contact for
control or signalling.
Function Treshold relay 2:
The function threshold relay is only available when in
parameter 3-3-2 Inlet the function valve on/off or prop.
is chosen.
Only after choosing the function “threshold relay”, the
following parameters will be visible
Par. 3-4-1-4-8-3 Treshold 2 on
Par. 3-4-1-4-8-4 Treshold 2 off
With this configuration of the selected digital output
(P4/P6 and FR4/FR6) you have an extra contact for
control or signalling.
