5-40 Function Relay
Array [8]
(Relay 1 [0], Relay 2 [1]
Option MCB 105: Relay 7 [6], Relay 8 [7] and Relay 9 [8]).
Select options to define the function of the relays.
The selection of each mechanical relay is realised in an array
parameter.
Option: Function:
[196] Fire Mode
[197] Fire Mode was Act.
[198] Drive Bypass
[211] Cascade Pump 1
[212] Cascade Pump 2
[213] Cascade Pump 3
6-01 Live Zero Timeout Function
Option: Function:
Select the time-out function. The function set in
par. 6-01 Live Zero Timeout Function will be
activated if the input signal on terminal 53 or 54
is below 50% of the value in par. 6-10 Terminal 53
Low Voltage, par. 6-12 Terminal 53 Low Current,
par. 6-20 Terminal 54 Low Voltage or
par. 6-22 Terminal 54 Low Current for a time
period defined in par. 6-00 Live Zero Timeout
Time. If several time-outs occur simultaneously,
the frequency converter prioritises the time-out
functions as follows:
1.
Par. 6-01 Live Zero Timeout Function
2. Par. 8-04 Control Timeout Function
The output frequency of the frequency converter
can be:
•
[1] frozen at the present value
•
[2] overruled to stop
•
[3] overruled to jog speed
•
[4] overruled to max. speed
•
[5] overruled to stop with subsequent
trip

6-02 Fire Mode Live Zero Timeout Function
Option: Function:
The function set in par. 6-01 Live Zero Timeout
Function will be activated if the input signal
on analogue inputs is below 50% of the value
defined in parameter group 6-1* to 6-6*
"Terminal xx Low Current” or “Terminal xx
Low Voltage" for a time period defined in
par. 6-00 Live Zero Timeout Time.

6-10 Terminal 53 Low Voltage
Range: Function:
0.07 V * [Application
dependant]
Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
par. 6-14 Terminal 53 Low Ref./Feedb.
Value.
6-11 Terminal 53 High Voltage
Range: Function:
10.00 V * [Application
dependant]
Enter the high voltage value. This
analog input scaling value should
correspond to the high reference/
feedback value set in par. 6-15 Terminal
53 High Ref./Feedb. Value.
