3. 62 series feedback potentiometer specifications

The 62 series feedback potentiometer is divided into two types: * * - S (non-linear, suitable for 90 series driven) and - F (0-10 K-line) * *, both of which can be used as voltage dividers. The feedback resistor is cut off with the stroke angle. The 160 ° motor is the full range, and the 90 ° asymmetric motor takes the first half and the symmetric motor takes the middle section. The core characteristics are as follows:

Voltage output: The TG terminal of the 160 ° motor outputs 4-96% of the YG terminal input, while the asymmetric terminal outputs 4-56% and the symmetric terminal outputs 24-76% at 90 °. The TY terminal outputs the reverse signal;

Diverting resistor: The driven 90 series motor requires a 142 Ω full stroke feedback resistor, which is matched with 187/274 Ω shunt resistors according to the model. The - F model does not have a suitable shunt resistor;

Resistance reading: Due to circuit protection, it is not possible to directly read the resistance, and the axis position needs to be tested through a voltage divider.

Model Naming Rules

This series of motor models consists of M+series+torque/reset+structure+auxiliary switch+suffix, and the core coding rules are as follows (taking M6184AXXXX as an example):

Second and third digits: 61/62 (series, 62 with feedback);

Fourth position: 8 (60lb in reset spring/150lb in no reset), 9 (300lb in no reset);

Fifth position: 2 (double end axis normally closed reset), 4 (no reset), 5 (normally closed reset);

Sixth position: A/D (0 auxiliary switches), B/E (1 auxiliary switch), C/F (2 auxiliary switches);

Suffixes: - S (non-linear feedback), - F (linear feedback).

Supporting accessories

This series of motors provides a full range of accessories, covering switch, adapter, connecting rod, protection, power supply and other needs. The core accessories and functions are as follows:

Auxiliary switch/potentiometer: 220736A (single switch)/220736B (dual switch) built-in kit (on-site installation); Q607 external auxiliary switch; Q181 auxiliary potentiometer (controls 1-4 90 series motors);

Adapter/crank arm: 220738A (shaft height increased by 3/4in, matching old model); 220741A (quick connect terminal to screw terminal); 221455A/7617ADW adjustable crank arm (can rotate downwards, no adapter required);

Transformer: 50017460-001 (24/120/230Vac input), 50017460-003 (120Vac input), both with 24Vac output;

Connecting rod/bracket: Q605 damper connecting rod (including crank arm); Q5001 water/steam valve connecting rod assembly; Q100 butterfly valve connecting rod (220738A required);

Protective accessories: 4074ERU waterproof kit (achieving NEMA 3 protection when not installed upright); ES650-117 explosion-proof shell (explosive environment, 7617DM coupling required, valve connecting rod not compatible);

Installation and wiring specifications

Basic installation requirements

Construction personnel: Professional trained technicians are required to disconnect all power sources before construction (motors with auxiliary switches may have multiple disconnection points);

Mechanical installation: The crankshaft must be installed horizontally, and the flange should be fitted with 1/4-inch machine screws/bolts; The factory ships motors without reset springs in the normally closed position (counterclockwise limit when viewed from the power end);

Environmental requirements: Keep away from acid mist and corrosive vapors; Use zinc/cadmium plated fasteners (stainless steel/brass prohibited) in high salt environments, paired with 220738A adapter;

Space requirements: Reserve space for accessory installation and maintenance. Liquid tight conduit joints are required for outdoor installation, and 4074ERU waterproof kits are required for non upright installation.

Adapter usage scenarios

220738A shaft height adapter is the core installation accessory, and must be used in scenarios such as Q607 external auxiliary switch, air door linkage requiring downward rotation/sufficient stroke, and all valve linkages except Q5001; Q5001 valve connecting rod does not require an adapter.

Wiring specifications

Compliance with local electrical regulations is required. When multiple motors are connected in parallel, the VA value of the power supply must meet all motor loads to avoid overload;

The motor terminal is a quick connect terminal on the top of the circuit board, and four screws in the junction box need to be removed before wiring;

Reverse rotation: Swap the W/B terminals for the 61 series, and swap the 1/2 terminals (motor rotation) and Y/G terminals (maintaining feedback synchronization) for the 62 series;

Transformer wiring: It is necessary to ensure that L1 corresponds to motor 4 terminals and L2 corresponds to motor 3 terminals to avoid reverse connection.

Core adjustment operation

Before all adjustment operations, the controller must be disconnected and the connecting rod must be removed. For motors with built-in transformers, only the power connection should be retained. It is forbidden to rotate the motor shaft by hand/wrench (which may damage the gear system and stroke limit contacts).

Stroke adjustment

61 series: From the power end perspective, the stroke potentiometer is located on the far left, with a clockwise full rotation of 160 ° and a counterclockwise full rotation of 90 °, with the middle position being the middle stroke;

62 series: Left stroke potentiometer and right sensitivity potentiometer, both potentiometers rotate synchronously, clockwise full 160 ° and counterclockwise full 90 °.

Auxiliary switch adjustment

The auxiliary switch is driven by an adjustable cam and supports 1 °/10 ° differential. The factory defaults to 30 ° on and 1 ° differential. Switching between different differential modes will cause the switch action to reverse. Adjustment steps:

Remove the junction box cover, disconnect the controller, and drive the motor to the auxiliary equipment action position;

1 ° Differential: Check the R-B contact for continuity. If it is open, turn the cam clockwise to close, and if it is closed, turn counterclockwise to disconnect;

10 ° Differential: Rotate the reset spring cam 180 ° to check the continuity of the R-B contact. If it is open, turn counterclockwise to close, and if it is closed, turn clockwise to disconnect;

Test the full stroke action, reset the controller and junction box cover.

62 series feedback potentiometer adjustment

Linear feedback: When there is no shunt resistor, the potentiometer directly outputs a linear signal of the shaft position;

90 series passive: A shunt resistor needs to be installed between the Y/G terminals to achieve a 142 Ω full stroke feedback resistor, with the resistor model referenced in Table 2;

Test: It is not possible to directly measure the resistance, and 5-10VDC needs to be applied through a voltage divider to test the linear change of the TG terminal voltage.

62 series driven control (multi motor synchronous)

The 62 series * * - S model * * can achieve passive control of 90 series motors. It is recommended that the number of slave stations should not exceed 6. Core specifications:

Motor matching: All driven motors must be of the same symmetrical/asymmetrical type;

Resistance configuration: Install shunt resistors according to the number of slave stations. One unit does not require a resistor, two units have 3500 Ω, three units have 2000 Ω, and six units have 800 Ω (symmetrical 90 ° stroke uses 5000/2400/1200 Ω, etc.);

Wiring rules: Connect one resistor to each of the T-G and T-Y terminals of the main motor 62 series; Connect one resistor to each R-B and R-W end of the 90 series substation;

Potentiometer setting: Adjust the stroke/sensitivity potentiometer (clockwise CW/counterclockwise CCW) according to the master/slave station stroke and symmetry type. It is not recommended to set it from 90 ° stroke to 160 ° stroke.

Replacement, Inspection, and Debugging

Replacement process

Wind door application: power off to dismantle old motor → determine adapter requirements (if the connecting rod is accessible and there is no jamming, no need) → directly install/match 220738A → install crank arm and connecting rod → debug;

Valve application: Q100/Q601/Q618 connecting rods require adapters, Q5001 does not require them → Honeywell V5011 (two-way)/V5013 (three-way) valves must use a 160 ° stroke motor → After installation, test the full stroke.

Inspection and debugging

Routine inspection: Check the firmness of mechanical connections → Test the full stroke of the motor for no jamming, and the connecting rod for no collision → Auxiliary switch accurately operates at the set position → Reset the spring type power-off verification for automatic return;

62 series special inspection: 3/4 terminal connected to 24Vac → Y/G terminal connected to 5-10VDC (Y+G -) → T/G terminal connected to voltmeter/oscilloscope → Drive motor full stroke, verify voltage linear change (160 °: 5-95% Vin, 90 ° asymmetric: 5-55% Vin, symmetric: 25-75% Vin);

Old model replacement: The motor that was originally connected to the R927C/R9107A relay is recommended to remove the relay and replace it directly with a 90 series Modutrol IV motor.
