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

Communications
Software.
Features
The M-2601 Autodaptive Regulator Control includes a user-defined Bandcenter and Voltage Regulation
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:
Bandcenter: Adjustable from 90.0 V to 135.0 V in 0.1 V increments.
Bandwidth: 1 V, predetermined by regulator step size.
VRQF: Adjustable from 0.4 V to 2.0 V in 0.1 V increments.
CT to VT Phasing Correction: Adjustable from 0° to +330° in 30° increments.
VT User Correction Voltage: VT correction from –12 V to +12 V in 0.01 V increments.
CT User Correction Multiplier: Adjustable from 50% to 200%, in 1% increments.
Voltage Limiting: Upper Voltage Limit adjustable from 90 V to 136 V, Lower Voltage Limit adjustable from
89 V to 135 V.
Line Drop Compensation: R & X (forward and reverse) adjustable from –24 V to +24 V in 1 V increments.
Intertap Minimum Delay: Adjustable from 5 seconds to 15 seconds in 0.1 second increments.
Raise/Lower Maximum Output Hold Time: Adjustable from 1 second to 15 seconds in 0.1 second
increments.
VAr Bias Setpoints:
Largest Cap Bank: Adjustable from 0 KVAr to 11057 KVAr.
Control Functions
Presettable Operations Counter: This software counter increments by one or two counts (user-selectable)
per close/open cam switch operation, and may be preset by the user from 0 to 999,999.
Resettable Operations Counter: A second software counter, similar to the operations counter, which may
be reset by the user.
Inputs
Control Voltage Input: Nominal 120 V ac, 60 Hz; operates properly from 80 V ac to 140 V ac. The burden
imposed on the input is 6 VA or less.
Motor Power Input: Nominal 120 V ac or 240 V ac, 60 Hz, at up to 6 A.
Line Current Input: Line drop compensation is provided by a current transformer input with a 0.2 A full scale
rating. The burden imposed on the current source is 0.03 VA or less, at 200 mA. The input will withstand 400
mA for two hours and 4 A for 1 second.
The unit will withstand twice the voltage input for one second, and four times the voltage input for one cycle.
Fuse protected for voltage above these limits.
