Works Globally, Right Out of the Box

The PULSE 400HD is our most versatile model yet. It’s designed to accept universal input voltage from 208V to 600V AC, 1Ph or 3Ph right out of the box for global compatibility. There’s no need for a step-down transformer or any additional configuration to achieve the required voltage.

Advanced, Programmable Speed Control

Program the RPM for the gearbox output of the open cycle and close cycle for constant door speeds that suit your installation. With its speed detecting encoder, the PULSE 400HD accommodates for the input voltage and provides reliable speed control throughout the operation, even if the voltages should fluctuate.

Adjustable Soft Start/Soft Stop

This feature offers smooth, controlled acceleration and deceleration of the door, and helps prolong the life of its mechanical parts. It also aids in the prevention of cable throw. The distance of both the acceleration and deceleration can be programmed to match the door requirements as needed.

Door Close Warning

When the closing timer is active, the red LED light flashes on your Stop & Go traffic light before the door closes. Programmable from 1 to 9 seconds, use this safety feature as an early warning for your workers. Best used with iControls^® TL Series LED Stop & Go traffic lights.

Reliable & Precise Encoder

Mounted inside the gearbox, the encoder enables easy limit setup and flexible left or right-side mounting. It supports advanced door functions including soft start/stop, dual open limits, and motion monitoring. If the door stops mid-cycle, the encoder detects the issue and halts operation to prevent further damage.

Chain Hoist Option

A manual chain hoist option is available for emergency backup operation. Once engaged via a lever at floor level, all electrical operation is disabled for operator safety. Default factory installation of the chain hoist is on the right-hand side of the operator, but it can be converted to the left-hand side on request. The door can also be operated using the included socket crankshaft.

Weather-Protect Option

For weather-resistant applications, iControls® recommends an upgrade. Standard PULSE operator motors are rated IP44, and could be vulnerable to water ingress. Furthermore, reflective photo-eye sensors can be affected by condensation on the reflector, preventing reliable operation in such conditions. iControls® offers a cost-effective weather-resistant upgrade that seals ingress points on the motor junction box, and includes a NEMA 4X through-beam sensor in place of the reflective photo-eye.
To order the weather-protect option, add the suffix “-WP” to the door operator part number.
