Test Menu
The Test menu provides various options for checking the protection release and CB.
Up to 7 options are available:
Name
Description
1. CB status
allows the user to view the CB state read by the protection release.
2. Auto Test
allows the display and led test to be performed
3. Trip test
allows an opening command to be transmitted to the CB
4. Gext( Idn) test
allows the operation of the Rc sensor to be checked
5. Zone selectivity
verification of the zone selectivity inputs and outputs
6. COM module
allows the contacts and controls of the CB to be checked
7. SIGNALLING/MM Test
module
allows output S51/P1 or 95S/98S to be checked and, if present, the state of K14/K15
The test menus of the modules and sensor Gext (Idn) are available if the accessories are connected and configured correctly in
the protection release.
3.11.1. Autotest
When autotest is activated, the display and leds will perform a test procedure allowing the user to check the state of the display
and operation of the leds themselves.
The procedure lasts several seconds and the sequence is as follows:
Phase ALARM and WARNING
leds
Display
1
On and fixed
ABB logo, the words “ABB Sace Spa“ and a message with the name of “PR332/P“ or
“PR333/P“
2
Off
Flashing backlighting (only if Vaux is present)
3
Normal operation
Contrast from 100% (display dark) to 0% (display light), after which the ABB words and
logo reappear
The test result and assessment are at the user’s discretion. Inform ABB if faults occur (Leds fail to function, display areas that
fail to function correctly).
3.11.2. Trip test
The state of CB opening can be checked by activating the trip test.
The protection release sends a command to the CT, which activates a CB opening mechanism. Opening of the circuit-breaker
denotes a positive test result.
WARNING: To perform the trip test, there must be no current circulating and the CB must be closed (failing this, the
Exception 6 error will appear).
3.11.3. Rc Test
The test option for sensor Rc is available if sensor Rc is present and correctly configured in the other menus of the protection
release.
To test the Rc sensor, select the Gext (Idn) test option from the test menu: the Rc test page will appear. Press the “iTest” key
again to perform the test.
A positive result will be indicated by the circuit-breaker opening within the previous entered time limits.
The test page for the Rc protection can also be accessed by pressing the “iTest” key for 7 seconds from the default page.
3.11.4. Zone selectivity
The tests commands are available with LSI and LSIG version releases. The menu is divided as to type of selectivity (S and G).
For both selectivity types, the user can:
- View the state of the inputs
- Force and release the outputs
WARNING: The override test for the selectivity outputs must be performed with the CB open: the Exception 6 error will
appear if the CB is closed or undefined.
If the CB is withdrawable, perform the test in the inserted or test position.
State assessment is at the user’s discretion.
