2- 2 M1 - Mains setup
Selecting the mains setup you access directly to the programmation parameters about the mains, like voltage and frequency limits.
All these parameters are shown in the following table:
POS.

A
Mains rated V
Allows you to set the rated voltage.
0-600 [Vac]
400
230
B
Mains high V
You can set the high threshold voltage; if the voltage
measured is higher than this value, the mains is
considered faulty and VERSO 50 activates the remote
start output (in automatic mode).
100-200 [%]

C
Mains low V
You can set the low threshold voltage; if the voltage
measured is lower than this value, the mains is
considered faulty and VERSO 50 activates the remote
start output (in automatic mode).
70-100 [%]

D
Mains rated F
Allows you to set the rated frequency.

E
Mains high F
You can set the high frequency threshold; if the frequency
measured is higher than this value, the mains is
considered faulty and VERSO 50 activates the remote
start output (in automatic mode).

F
Mains low F
You can set the low frequency threshold; if the frequency
measured is lower than this value, the mains is
considered faulty and VERSO 50 activates the remote
start output (in automatic mode).

G
KR delay
You can set a delay time for the closure of the mains
contactor. This time starts from when the VERSO 50
opens the generator contactor (software interlock
function).

H
Mains OK
It is the delay time after which, if the mains returns within
the limits set (see parameters B, C, E, F), it’s considered
stable and the mains contactor is closed, then the remote
start output is deactivated (in automatic mode).
0-9999 [s]

I
Faulty mains
It is the delay time after which the mains is considered
faulty, compared with the limits specified in parameters B,
C, E, F. This parameter is used to filter any temporary
instability of the mains.

J
System type
You can set the type of system.
If you set it to Monophase, the system is considered as
single-phase.
If you set it to Threephase, the system is considered as
three-phase.

K
Start delay
Delay time to activate the remote start output in automatic
mode when faulty mains conditions are true.
0-59 [s]

L
Stop delay
Delay time to remove the remote start output in automatic
mode when mains within limits conditions are true. Load
switching on mains side does not wait this delay.

KR alarm ON
If On, the alarms set as “Global KR” cause the opening of
the mains contactor.

If On, the mains is considered with neutral connected. If
Off, the mains is considered without neutral.
