10. To proceed to the CONNECT position, the
circuit breaker must indicate OPEN on the HMI
touchscreen. If the circuit breaker is not in OPEN
status, SIERS will not allow racking to the circuit
breaker to CONNECT position.
11. Touch CONNECT on the HMI display to rack the
circuit breaker to the CONNECT position.
Note: It is not necessary to maintain constant
pressure on the touchscreen. Upon initiating this
command, the amber indication (for TEST) will
turn off. When the circuit breaker reaches the
CONNECT position, the red indication (for
CONNECT) will turn on.
12. When the circuit breaker is in the CONNECT
position, it can be operated to CLOSE or OPEN
from the HMI display in the portable carrycase.
13. To rack the circuit breaker from CONNECT to
TEST or DISCONNECT, the circuit breaker must
be tripped OPEN. The OPEN command can be
initiated from the HMI touchscreen If the circuit
breaker is not in OPEN status, SIERS will not
allow racking to the circuit breaker from
CONNECT to the TEST or DISCONNECT position.
Auxiliary truck racking operation
The following describes the sequence of operation
for racking voltage transformer, control power
transformer, or fuse truck. Always refer the safety
guidelines and recommendations outlined the
safety section of this manual. Also, refer to
the instruction manuals for specific switchgear:
GM-SG non-arcresistant switchgear (E50001-F710-
A230-XX-XXXX) and GM-SG-AR arc-resistant
switchgear (E50001-F710-A254-XX-XXXX) for
additional information.
Tip(s): When control power is not available in
the switchgear, then use 120 VAC power via
external power outlet in the electrical room or
area to operate SIERS 2.0 to remotely rack the
auxiliary truck.
