On terminals X1 or J2connector 6 of the following 28 signals can be selected from the display
(access only with password): MENU / PARAMETER MENU / LEVEL 2: SERVICE.
0 - No signal
1 - Buzzer
2 - General alarm (NO)
3 - Load on utility
4 - Stop operation
5 - Load on inverter
6 - Utility failure
7 - DC overvoltage
8 - Low battery
9 - Overload
10 - Overtemperature
11 - Inverter utility not syncrony
12 - Bypass locked
13 - Bypass utility failure
14 - Rectifier utility failure
Some UPS functions can be activated by parameters (access with password only) when an external
NO contact is closed on:
No function
Inverter OFF
Print all
External bypass ON
Voltage free contacts:
Gen Set signaling
If an Emergency generator set supplies the UPS in case of utility failure and the generator is particularly
unstable in frequency, it should be suitable to install the signal "generator on" on terminals X1 / 11, 22
(Normally Open voltage-free contact) or on connector J2 / 11, 24 (see Fig. 5.4-1 / X1 and J2).
Since the Parameter for of the reading of the Generator function is password protected, call the nearest
Service Center for it's activation.
When this contact closes, it causes the change of certain settable functions such as:

Enabling or disabling of synchronization and consequently the load transfer to generator.

The battery recharge inhibition during the generator operation, or after what delay from generator
start the battery will start to be recharged.
