On terminals X1 or J2 connector 6 of the following 28 signals can be selected from the display
(access only with password): SETUP / SETUP / LEVEL 2: SERVICE.
0 - No signal
1 - Buzzer
2 - General alarm (NO)
3 - Load on mains
4 - Stop operation
5 - Load on inverter
6 - Mains failure
7 - DC overvoltage
8 - Low battery
9 - Overload
10 - Overtemperature
11 - Inverter-mains not syncrony
12 - Bypass locked
13 - Bypass mains failure
14 - Rectifier mains 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 signalling
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. 10.2.1-1 / X1 and J2).
Since the Parameter for of the reading of the Generator function is password protected, call the nearest
Service Centre for it's activation.
When this contact closes, it causes the change of certain settable functions such as:
•
Enabling or disabling of synchronisation 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.
Consult your nearest Service Centre for more information.
In a Parallel System a separate NO (Normally Open) contact must be connected to
each individual unit.
