Setup Configurations

Portable HMI Setup
SIERS 2.0 Portable HMI setup is supplied with a
motor fixed-mounted on the racking mechanism for
each circuit breaker compartment, and optionally
available for voltage transformer, control power
transformer, and fuse auxiliary truck compartment.
It consists of the following key components:
• One light-weight portable carrycase will be
equipped with HMI, logic controller, components,
and a 30-ft cord to connect to the associated
removable element to be racked. One carrycase
will be shipped with the order (see Figure 1).
• Each removable element compartment is
equipped with a motor and limit switches
integrated into racking mechanism assembly
(see Figure 5).
First, the motor is operated, controlled, and
protected by the HMI, logic controller and the other
control devices in the portable carrycase simply by
plugging the 30-foot cable into a connector of the
removable element located on of the low voltage
compartment door. Then the operator plugs the
other end of the 30-foot cable into receptacle on the
side of the carry case, locates the case outside of
the arcflash boundary, and performs open or close
function and/or the racking process.

Local HMI Setup
This more advanced set up of SIERS 2.0 includes
a stepper motor fixed-mounted on the racking
mechanism for each circuit breaker compartment,
and optionally available for voltage transformer,
control power transformer auxiliary truck
compartment. This step consists of the following
key components:
• CPU controller along with portable HMI installed
in low voltage compartment or control cabinet
mounted on side of switchgear for indoor
enclosure (see Figure 2).
• Stepper motor integrated into racking mechanism
assembly located inside the circuit breaker and
optionally in the auxiliary truck compartments
(see Figure 15).
The stepper motors are daisy-chain connected
via communication cable to a single CPU along
with control devices located either in an empty
compartment in the GM-SG lineup, or in a separate
cabinet located the sidewall of GM-SG or GM-SG-AR
lineup. One handheld HMI is also provided and
located where the CPU is.
