14. Annex 1: Supervisor alarms - T2S ETH
This is the list of alarms issued by supervisor. Other alarms are issued by other modules (see section 15, page 72).
The supervisor is able to generate alarms that are related to the system, to inverter modules, or to itself. Alarms related
to inverters will be seen as system alarms when module alarm is present on all inverters. Each alarm has a priority
level. The level can be (disabled, event, minor, major). If the level can be configured in user interface, then it is marked
as “mappable”.
System Alarms
Text ID Name Level Def. Map Description
256 MBP Engaged mappable major
Digital input 1 is in low state and digital input 1 is
used for MBP signaling.
257 Surge Arrester mappable minor
Digital input 2 is in low state and digital input 2 is
used for surge arrester signaling.
258 Redundancy Lost mappable minor
Redundancy is configured and redundancy is lost
on any output group.
259 Redundancy +1 Lost mappable minor
Redundancy is configured and more than
redundancy is lost on any output group.
260 Main Source Lost mappable major
Any of the groups from main source is not conform.
Example: there are 3 AC input groups and AC
source is main source. If one AC input is offline, the
alarm is triggered.
261
Secondary Source
Lost
mappable minor
Any of the groups from secondary source is not
conform.
262 AC Source Lost mappable R3 Any AC input group is not conform.
263 DC Source Lost mappable disabled Any DC input group is not conform.
264 AC Source Not Sync mappable minor
Any AC input group is not synchronized with AC
output or has an out of range frequency.
265 DC Source Low mappable major
Any DC input group has a voltage lower that defined
threshold.
266 Output Saturated mappable disabled
The load on any output group is higher than the
saturation threshold (80% of configured output
power).
267 Output Overloaded mappable major
The load on any output group is higher than the
configured output power.
268 Output Failure mappable major
Any output group has 0 seen modules, or no
module running (and they are not manually off).
269 System Started event System just started.
272 Missing Module event No module is detected on system bus.
273 New Module event All modules have just been detected on system bus.
274 Manually OFF mappable disabled All modules outputs are manually turned off.
275 Output Fault event
All modules outputs are turned off because of a
fault.
276 Brownout Derating event
All modules AC inputs are derated because of a
brown-out.
