Linear 2520-536 1HP 115V 1-Phase VS-GSLG Control
The Linear 2520-536 control assembly is a replacement controller for 1 HP, 115V, single-phase VS-GSLG variable-speed slide gate operators. The VS-GSLG series is a heavy-duty slide gate operator family that uses a variable-speed design, so the controller must match the exact motor horsepower, incoming power, and operator generation. A control replacement may be needed after electrical failure, water or insect damage, impact damage, output failure, or a diagnosed variable-speed control fault. However, many slide gate problems are caused by power supply issues, limit problems, chain/drive drag, safety-device faults, accessory wiring, or a failing motor, so the system should be diagnosed before replacing the control. After installation, the operator should be checked for proper speed profile, limit operation, obstruction response, and monitored safety-device operation.

Technician Note
Match this control by the operator nameplate and parts diagram, not by appearance alone. Voltage, phase, horsepower, controller generation, terminal layout, and safety-device wiring must all be correct before power is applied.
Before Ordering
- Confirm the manufacturer part number on the existing part or parts diagram.
- Compare the product function, mounting style, wiring, and included components to the current installation.
- Do not assume similar-looking Linear, OSCO, or Linear PRO Access parts are interchangeable.
- Verify voltage, phase, horsepower, and operator series on the nameplate.
- Confirm monitored safety-device wiring and accessory wiring before returning the gate to service.
Professional Advisory
This product may involve high-voltage wiring or safety-critical gate operation. Installation, diagnosis, and final safety testing should be performed by a qualified gate technician.
Product Q&A
What is the 2520-536 control used for?
It is a 1 HP, 115V, single-phase control assembly for select Linear / OSCO VS-GSLG variable-speed slide gate operators.
Can it replace another VS-GSLG controller number?
Only if the voltage, phase, horsepower, and operator generation match. Other VS-GSLG controller numbers are different configurations.
Why is horsepower important on this part?
The controller must match the motor and variable-speed system. Using the wrong horsepower control can cause poor operation or equipment damage.
What should be checked after installation?
Check limits, speed profile, gate travel, safety-device inputs, accessory wiring, and obstruction response before returning the gate to use.
Is this safe for DIY replacement?
No. This is high-voltage commercial gate operator equipment and should be handled by a qualified gate technician.
