INPUTCodeDefinition AdjustmentRange M-G M-M
INH InhibitionoftheAutomaticOperation:
All automatic commands relative to the transfer switch, but excluding
the Genset Start signal, will be inhibited.
Note: With INH closed, the generator will start if the network is lost
but the switch will not transfer position.
NO / NC
(Normally Open or
Normally Closed)
• •
TON TestOn-Load:
Activates an on load test. Retransfer remains locked until the contact is opened.
NO / NC •
TOF TestOff-Load:
Activates an off load test. This will start and stop the generator without
transferring the load to S2.
NO / NC •
EON ExternalTestOnloadoperationrequest,(delayable):
Activates an operating cycle depending on time delays E1T, E2T, E3T.
These time delays must be set in the TIMERS menu. Refer to the
graphs below for operation details.
Note: This input function together with the associated time delays
(E1T, E2T, E3T) are particularly useful for peak shaving.
NO / NC •
EOF ExternalTestOffloadoperationrequest,(delayable):
Activates "Start Gen" contact according to time delays. These
time delays must be set in the TIMERS menu E5T, E6T et E7T. The
operation is the same as for EON but without the load switching over
to the Genset, (S2).
NO / NC •
RTC Remotetransferbacktotheprioritysource:
This is the same function as "RETRANS" cleared with the keypad. This
variable in the SETUP menu must be “YES” to validate the operation
through this input.
NO / NC • •
PRI PrioritytoSource2:
By default the priority source on the ATySp is S1. Input PRI will set the
priority to S2. This input takes priority over PRIO NET in the SETUP menu.
NO / NC •
SS1
SS2
VoltageStabilisationtimedelayrelaybypass:
These inputs allow to initiate the transfer from one source to the other
before the end of the time delay 1RT/2RT/2AT.
NO / NC • •
AL1
AL2
ExternalAlarmforSource1andSource2:
This input will ash the “Fault LED” on the front of the ATySp ATS
controller and will indicate F12 ALR - 1 / F22 ALR - 2 on the screen.
This message will disappear when the external alarm is cleared by
opening the input contact.
Note: These alarms do not trigger any position change in the
switch but the product not available output will be activated.
NO / NC • •
FT1
FT2
ExternalFaultSource1orsource2withzeroreturn:
This input will ash the “Fault LED” on the front of the ATySp ATS
controller and will indicate F11 FLT - 1 / F21 FLT - 2 on the LCD screen.
This message will disappear after validation and RESET through input
RST, by changing the selector switch from AUT to Manu and back to
AUT or via communication after the fault has been cleared.
Note: Immediately upon activation of one of these inputs the ATySp
will changeover to the 0 position. Time delays 10T or 20T time delay
will not be considered.
NO / NC • •
MSR HoldonS2(Genset)withprioritytoTONandEON:
During a Test On Load (TON) or an external Test On Load (EON), validating
MSR will force the ATySp to remain on source 2 for as long as TON or EON
are active. The switch will remain on S2 even if the Genset supply is lost.
NO / NC •
0A1
0A2
DefineSource1and/orSource2asavailable:
This is an external input used to bypass the internal voltage sensing
and timers. These inputs will dene S1 and/or S2 available immaterial
of the value and immaterial of timers 1RT, 2RT, 2AT.
NO / NC • •
RST FaultReset:
This input may be used to reset a fault condition after the fault has
been cleared. Faults may also be reset through communication or by
shifting the front selector switch on the ATySp from AUT to Manu and
back to the AUT position.
NO / NC • •
LSI PretransfersignalLSCtimedelay(loadshedding1)bypass:
This input will bypass the LSC time delay, thereby conrming that the load is
OK (Shed or within an acceptable range) and the changeover to source 2 may
begin immediately. Only visible after activating at least one output as LSC.
NO / NC • •
