GENERAL INFORMATION

INTRODUCTION

This manual contains installation, operation, and maintenance and repair instructions for Fincor Series 2610 MKII /

2601 Single-Phase Adjustable-Speed DC Motor Controllers. A parts list, ratings and specifications, and drawings are

also included.

GENERAL DESCRIPTION

Series 2610 MKII / 2601 Controllers statically convert AC line power to regulated DC for adjustable-speed armature

control of shunt-wound and permanent-magnet motors.

Series 2610 MKII / 2601 Controllers comply with applicable standards established by the National Electrical Code and

NEMA for motor and industrial control equipment. The controllers are Underwriters Laboratories Listed (File No.

E184521) UL/cUL.

MOTOR SELECTION

Series 2610MKII / 2601 Controllers control the operation of general purpose DC motors designed for use with solid-

state rectified power supplies. The motor may be shunt-wound, stabilized shunt-wound, or permanent magnet. For

maximum efficiency, the motor should be rated for operation from a NEMA Code K power supply.

SECTION II

INSTALLATION

Before starting the installation, read this section thoroughly. In addition, a thorough review of the Ratings and

Specifications (Section VI) is recommended. The following installation guidelines should be kept in mind when

installing the controller.

INSTALLATION GUIDELINES

1. CONTROLLER MOUNTING - The controller may be mounted either vertically or horizontally. However, never

mount the controller upside down, immediately beside or above heat generating equipment, or directly below water or

steam pipes.

The controller must be mounted in a location free of vibration.

Multiple controllers may be mounted side by side, as close to each other as the mounting feet will allow.

The minimum clearance at the top and bottom of the controller may be as narrow as the conduit fittings allow.

2. ATMOSPHERE - The atmosphere surrounding the controller must be free of combustible vapors, chemical fumes,

oil vapor, and electrically conductive or corrosive materials.

The air surrounding an enclosed controller must not exceed 40 degrees C (104 degrees F), and the air surrounding an

open-chassis controller must not exceed 55 degrees C (131 degrees F). Minimum air temperature is 0 degree C (32

degrees F) for enclosed and open-chassis controllers.

3. CONTROLLER CONSTRUCTION - The controller base is made of die-cast aluminum with a powdered epoxy

finish, and the cover is made of a die-cast aluminum alloy.

The controller enclosure is totally enclosed, non-ventilated, and complies with NEMA Type 4 and 12 standards. There

is an oil resistant synthetic rubber gasket between the cover and base. Those models with integral operator controls

include flexible boots to seal the switches, and a seal for the MOTOR SPEED potentiometer.

4. LINE SUPPLY - The controller should not be connected to a line supply capable of supplying more than 100,000

amperes short-circuit current. Short-circuit current can be limited by using an input supply transformer of 50 KVA or

less, or by using correctly sized current limiting fuses in the supply line ahead of the controller. Do not use a

transformer with less than the minimum transformer KVA listed in Table 8, page 31.

If rated line voltage is not available, a line transformer will be required. If the line supply comes directly from a

transformer, place a circuit breaker or disconnect switch between the transformer secondary and the controller. If power

is switched in the transformer primary, transients may be generated which can damage the controller. See Table 8 (page

31) for minimum transformer KVA.

Do not use power factor correction capacitors on the supply line to the controller.

A 20 Joule metal oxide varistor (MOV) is connected across the controller terminals. If higher energy transients are

present on the line supply, additional transient suppression will be required to limit transients to 150% of peak line

voltage.

BOOK 0959

When a 115 VAC line supply is used, connect the white (common) wire to Terminal L2 and connect the remaining

(hot) wire to Terminal L1.

5. ISOLATION TRANSFORMER - While not required, an isolation transformer can provide the following

advantages:

a. Reduce the risk of personal injury if high voltage drive circuits are accidentally touched.

b. Provide a barrier to externally generated AC supply transients. This can prevent controller damage from abnormal

line occurrences.

c. Reduce the potential for damaging current if the motor armature, motor field, or motor wiring becomes grounded.

6. GROUNDING - Connect the green or bare (ground) wire of the line supply to the ground screw located near the top

conduit entry hole in the controller base. Then ground the controller base by connecting the ground screw to earth

ground.

The motor frame and operator control stations must also be grounded.

Personal injury may occur if the controller, motor, and operator stations are not properly grounded.

7. WIRING PRACTICES - The power wiring must be sized to comply with the National Electrical Code, CSA, or

local codes. Refer to the controller data label for line and motor current ratings.

Do not use solid wire.

Signal wiring refers to wiring for potentiometers, tachometer generators, and transducers. Control wiring refers to

wiring for operator controls, e.g., switches and pushbuttons. Signal and control wiring may be run in a common

conduit, but not in the same conduit as the power wiring. In an enclosure, signal and control wiring must be kept

separated from power wiring and only cross at a 90 degree angle to reduce electrical noise.

If shielded wire (such as Alpha 2422 - two conductor, 2423 - three conductor, 2424 - four conductor) is used for the

signal and control wiring, connect the shields to chassis ground (ground screw on the controller base) and tape the

opposite ends of the shields. Twisted cable is also suitable for signal and control wiring.

Two 3/4-14 NPT threaded holes are provided for conduit entry, one each in the top and bottom of the controller.

BOOK 0959

INSTALLING THE CONTROLLER

1. Remove the controller front cover (if used) by removing the four cover screws.

2. Check components in the controller for shipping damage. Report shipping damage to the carrier.

3. Check the controller and motor data labels to be sure the units are electrically compatible.

4. Be sure the controller has been calibrated correctly for the motor being used. Calibration is performed by

changing the position of a Jumper J4 on the controller control board to comply with Table 2. To change the position

of Jumper J4, pull the jumper from the control board and then push it onto the appropriate two pins on the board. For

the location of J4, see Figure 23 (page 37).

a. Select the position closest to the motor nameplate armature current rating.

5. Check the positions of Jumpers J1, J2, and J3 on the control board. For the locations of J1, J2, and J3, see Figure 23,

page 37. For a 230 VAC line supply and a 180V armature motor, Jumper J1 must be in the 230V position, and Jumpers

J2 and J3 must be in the 180V position. For a 115 VAC line supply and a 90V armature motor, J1 must be in the

115V position, and J2 and J3 must be in the 90V position. To change the position of J1, J2, or J3 pull the jumper

from the control board and then push it onto the appropriate pins on the board.

NOTE: If Option 1001 (Armature Contactor, Unidirectional), 1004 (Armature Contactor, Reversing), or 1775 (Signal

Interface) is to be installed in the controller, do not offset the five-position plug (supplied with the option) at Connector

J1 on the control board. Do not confuse Connector J1 with Jumper J1. Refer to the Instruction Sheet (ISP0703,

ISP0666, ISP0653, respectively) supplied with the option for connection instructions.

6. The controller may be surface mounted or panel mounted as shown in Figure 1, page 7. Mount the controller.

Mounting dimensions are shown in Figure 2, page 8.

7. Conduit entry is made by punching out the knockout at the top or bottom of the controller base. To prevent

component damage from knockout fragments, apply masking tape to the inside of the knockout before punching.

8. Connect the power wiring to Terminals L1, L2, A1 (+), A2 (-), F+ and F-. Be sure to observe Installation Guidelines

4 and 7 on pages 3 and 4. If half-wave shunt field voltage is desired, connect one of the motor shunt field leads to

Terminal F/2 (see Table 12 on page 34).

NOTE: Low inductance motors require a full-wave field to prevent current instability.
