5.11.9. MODBUS TCP/IP
If the ATS was purchased with the Modbus TCP/IP Ethernet remote communication
Option, the com port on the GHC can be enabled by setting the value to YES.
5.11.10. ENABLE SECURITY BYPASS
When the security bypass feature is enabled, it allows the ATS to be operated without a
security login. The TSC 900 is supplied from the factory with this feature enabled to allow
initial ATS operation during commissioning without the need for a security login. It is
recommended to disable this feature once the ATS is turned over to the end user so that
desired security passwords can be used. To enable the security bypass feature set the
value to YES.
5.11.11. ENABLE NEUTRAL DELAY BYPASS
The TSC 900 transfer switch controller contains “NEUTRAL DELAY BYPASS” logic,
which allows a shorter neutral delay timer period during transfer if the load bus voltage
falls to safe levels before the transfer sequence is completed. This feature is user
programmable and allows 2 different functional settings which are described below:
NO (DISABLED): The transfer switch neutral delay period will operate as per
the Neutral Delay Timer setting.
YES (ENABLED): The transfer switch neutral delay period will be bypassed if
the load bus voltage falls to safe levels before the transfer sequence is
completed.
Note: the neutral delay timer will be bypassed in either “Enabled” or “Disabled” modes
should the originating source voltage be in a de-energized (i.e. blackout) state prior to
transfer.
5.11.12. ENABLE TRANSFERS TO SRC 1 (UTILITY)
The TSC 900 transfer switch controller contains “ENABLE TRANSFERS TO UTILITY”
logic. This feature is user programmable and allows 2 different functional settings which
are described below:
NO (DISABLED): The transfer switch will be inhibited from transferring to the
Utility position.
YES (ENABLED): The transfer switch will be permitted to transfer to the Utility
position.
