The following table indicates the display messages of the various timers and operations states:

Description
Corresponding timer parameter
Note
S1 Start delay
Source 2 has failed, and now the S1 start delay timer is
running.
"S1 start delay time"
(parameter 4149)
Gen-Gen mode only
S2 Start delay
Source 1 has failed, and now the S2 start delay timer is
running.
"S2 start delay time"
(parameter 3330)
Util-Gen and Gen-Gen
mode only
S1 Stable timer
The transfer from Source 2 to Source 1 is delayed, to
permit stabilization of Source 1 before a re-transfer is
made. If Source2 fails during timing, a re-transfer to
Source 1 will be performed immediately.
"S1 Source Stable time"
(parameter 3333)
S2 Stable timer
The transfer from Source 1 to Source 2 is delayed, to
permit stabilization of Source 2 before a transfer is made.
"S2 Source Stable time"
(parameter 3332)
S1 Cooldown
Engine runs unloaded, after a retransfer to Source 2 has
been made. This is to ensure that engine 1 has enough
time to cool down.
"S1 cooldown time"
(parameter 3343)
Only for Gen-Gen appli-
cations
S2 Cooldown
Engine runs unloaded, after a retransfer to Source 1 has
been made. This is to ensure that engine 2 has enough
time to cool down.
"S2 cooldown time"
(parameter 3344)
Util-Gen and Gen-Gen
mode only
Load on S1
Source 1 is connected to the load.
-
Starting S2
Engine 2 is being started.
"S2 Start fail delay time"
(parameter 3331)
Load on S2
Source 1 has failed, and Source 2 is connected to the load.
-
Load test
The control is in “Load Test” mode. A Source 1 failure is
simulated (duplicates operation of Source 1 failure).
Load test activation either via
"Load test" Button or via
"Load Test - LogicsManager"
(parameter 12640)
No load test
The ATS system is in "No load Test" mode. This means,
that the engine runs unloaded, and no transfers will take
place. This test mode is used to ensure proper operation
of the engine.
No load test activation either
via "Engine test" Button or via
"No Load Test – LogicsMan-
ager" (parameter 12650)
Elevator signal
The Elevator pre-signal timer is running. This message
only occurs, if the "Elevator pre-signal" feature is activat-
ed and BOTH sources are available. If only one source is
available (like in an emergency case) the elevator pre-
signal timer will automatically be bypassed.
"Elevator pre-signal duration"
(parameter 4491)
Starting S1
Engine 1 is being started.
"S1 Start fail delay time"
(parameter 3341)
Only for Gen-Gen appli-
cations
Wait S1 to open
A command is issued by the ATS Controller to open the
ATS switch from Source 1 position
"Limit switch reply timeout"
(parameter 3428)
Wait S2 to open
A command is issued by the ATS Controller to open the
ATS switch from Source 2 position
"Limit switch reply timeout"
(parameter 3428)
Wait S1 to close
A command is issued by the ATS Controller to close the
ATS switch into Source 1 position
"Limit switch reply timeout"
(parameter 3428)
Wait S2 to close
A command is issued by the ATS Controller to close the
ATS switch into Source 2 position
"Limit switch reply timeout"
(parameter 3428)
Rem. peak shave
"Remote peak shave" mode is active
Remote peak shave activation
via "Remote peak shave -
LogicsManager"
(parameter 12630)
Motor Load Disc.
The Motor Load Disconnect timer is running. This mes-
sage only occurs, if the "Motor load disconnect" feature is
activated.
"Disconnect time S1→S2" (pa-
rameter 4551) and/or
"Disconnect time S2→S1" (pa-
rameter 4552)
Inhib. XFR to S1
A transfer to Source 1 is inhibited although Source 1 is
available. In the case of a Source 2 failure, a transfer to
Source 1 takes place, even the transfer is inhibited
"Inhibit transfer to Source 1"
activation via "Inhib. XFR to
Source 1 - LogicsManager"
(parameter 12610)
