M-2601 Autodaptive Regulator Control
The M-2601 Autodaptive®Regulator Control is a unique microcontroller-based solution to regulator control
requirements. Using conventional Siemens Regulator inputs, the control accomplishes regulator control,
based on voltage. Communication and control features of the M-2601 are accomplished utilizing either
M-2802 SLIMcom®for Windows™from a PC platform, or M-2808 SLIMcom for Visor™Communications
Software.
Features

Quality Factor (VRQF) that permits optimization of the tapchanging process. Also included are: a DRAG
HANDS RESET button, a VOLTAGE SOURCE selector switch and binding posts for Motor Power, Control
Voltage and Voltage Test. Separate fuses for motor power, control, relays and the neutral circuit are located
on the rear of the panel.
Configurable setpoints include:

VRQF is the RMS deviation in the fundamental component of an AC voltage from a desired AC voltage. It is computed as the
square root of the sum of the squares of deviations in the fundamental component of the voltage from the desired value. The
sum is computed as a running recursive average of frequently taken samples of the fundamental component, obtained in at
least one full cycle of the wave. The time constant of the recursive computation is 6 hours. The recursive average takes at
least six hours to settle to a proper sum, and is generally never stopped, once started.

WARNING
DANGEROUS VOLTAGES, capable of causing deat or serious
injury, are present on t e external terminals and inside t e equip-
ment. Use extreme caution and follow all safety rules w en an-
dling, testing or adjusting t e equipment. However, t ese internal
voltage levels are no greater t an t e voltages applied to t e exter-
nal terminals.
DANGER! HIGH VOLTAGE
– This sign warns that the area is connected to a dangerous high voltage, and you
must never touch it.
PERSONNEL SAFETY PRECAUTIONS
The following general rules and other specific warnings throughout the manual must be followed during application,
test or repair of this equipment. Failure to do so will violate standards for safety in the design, manufacture, and intended
use of the product. Qualified personnel should be the only ones who operate and maintain this equipment. Beckwith
Electric Co., Inc. assumes no liability for the customer’s failure to comply with these requirements.
–This sign means that you should refer to the corresponding section of the operation
manual for important information before proceeding.
Always Ground the Equipment
To avoid possible shock hazard, the chassis must be connected to an electrical ground. When servicing
equipment in a test area, the Protective Earth Terminal must be attached to a separate ground securely
by use of a tool, since it is not grounded by external connectors.
Do NOT operate in an explosive environment
Do not operate this equipment in the presence of flammable or explosive gases or fumes.To do so would
risk a possible fire or explosion.
Keep away from live circuits
Operating personnel must not remove the cover or expose the printed circuit board while power is ap-
plied. In no case may components be replaced with power applied. In some instances, dangerous volt-
ages may exist even when power is disconnected.To avoid electrical shock, always disconnect power and
discharge circuits before working on the unit.
Exercise care during installation, operation, & maintenance procedures
The equipment described in this manual contains voltages high enough to cause serious injury or death.
Only qualified personnel should install, operate, test, and maintain this equipment. Be sure that all per-
sonnel safety procedures are carefully followed. Exercise due care when operating or servicing alone.
Do not modify equipment
Do not perform any unauthorized modifications on this instrument. Return of the unit to a Beckwith
Electric repair facility is preferred. If authorized modifications are to be attempted, be sure to follow
replacement procedures carefully to assure that safety features are maintained.

PRODUCT CAUTIONS
Before attempting any test, calibration, or maintenance procedure, personnel must be completely familiar
with the particular circuitry of this unit, and have an adequate understanding of field effect devices. If a
component is found to be defective, always follow replacement procedures carefully to that assure safety
features are maintained. Always replace components with those of equal or better quality as shown in the
Parts List of the Instruction Book.
Avoid static charge
This unit contains MOS circuitry, which can be damaged by improper test or rework procedures. Care
should be taken to avoid static charge on work surfaces and service personnel.
Use caution when measuring resistances
Any attempt to measure resistances between points on the printed circuit board, unless otherwise noted
in the Instruction Book, is likely to cause damage to the unit.
