Safety Precautions
DANGER
The equipment controlled by the Micro-AT Source-Transfer Control operates
at high voltage. Failure to observe the precautions below will result in serious
personal injury or death.
Some of these precautions may differ from your company’s operating procedures
and rules. Where a discrepancy exists, follow your company’s operating procedures
and rules.
1. QUALIFIED PERSONS. Access to a Micro-AT
Source-Transfer Control must be restricted only to
qualified persons. See the “Qualified Persons”
section on page 2.
2. SAFETY PROCEDURES. Always follow safe
operating procedures and rules.
3. PERSONAL PROTECTIVE EQUIPMENT. Always
use suitable protective equipment, such as rubber
gloves, rubber mats, hard hats, safety glasses, and
flash clothing, in accordance with safe operating
procedures and rules.
4. SAFETY LABELS. Do not remove or obscure any
of the “DANGER,” “WARNING,” “CAUTION,” or
“NOTICE” labels.
5. OPERATING MECHANISMS. Do not remove or
disassemble operating mechanisms or remove
access panels on the Micro-AT Source-Transfer
Control unless directed by S&C Electric Company.
6. ENERGIZED COMPONENTS. Always consider all
parts live until de-energized, tested, and grounded.
The Integrated Power Module (IPM) contains
components that can retain a voltage charge for
many days after the Micro-AT Source-Transfer
Control has been de-energized and can derive a
static charge when in close proximity to a high-
voltage source. Voltage levels can be as high as the
peak line-to-ground voltage last applied to the unit.
Units that have been energized or installed near
energized lines should be considered live until
tested and grounded.
7. MAINTAINING PROPER CLEARANCE. Always
maintain proper clearance from energized
components.

To perform the eld adjustment and programming procedures outlined in the following
steps, the correct access-code number must be entered when so directed. Please contact
S&C Electric Company for the access-code number.
NOTICE
Always normalize the left and right sources and set the base voltages on Phase
2 of the left and right sources after executing CONFIG: RESTORE VALUES. The
following parameters (even if the display shows correct values) also must be manually

and selecting the communications card bit rate are discussed below.
(d) Normalize the left and right sources (unless CONFIG: VOLTAGE
SENSING has been factory-set for 2 WIRE voltage sensing).
Note: Each source must be normalized to compensate for any output-
voltage magnitude unbalance and/or phase-angle unbalance between
the voltage-sensing devices on that source. Each source should be in its
known normal state, so that unusual system conditions aren’t calibrated
out.
Here, for example, is the display for CONFIG: NORMALIZE LEFT:
ECONFIG: ENORMALIZEELEFT
ENORMALIZEEEEEEEEEECHANGE
Press the <Change> key. If the display prompts you to reenter the access-
code number, do so. The following display will appear:

NOTICE
A source can be normalized only if each phase has measurable voltage and
its sequence of rotation is the same as on the other source. If normalizing
can’t be performed, one of the following messages will be displayed:
CANNOT NORMALIZE CANNOT NORMALIZE
PHASE VOLT(S) TOO LOW OPPOSITE PHASE ROTATION
If either of these messages is displayed, contact your nearest S&C Sales
Office.
