Request Information

The ES-90 control box is an energy saving control unit designed to be used for controlling exhaust fans in vehicle exhaust systems, with or without a particle filtration system. Together with optional activation devices such as a pressure switch, wireless control, or micro switch, this energy saving controller makes a fully automatic system for the control of the vehicle exhaust fan. The controller can be set for both manual or automatic control of the fan. Depending on the configuration of a system, several options for switches and remote start functions are available. The two most common switches used, are the MSR-24/2 or BRC-MS micro switch mounted on an exhaust hosereel or balancer to start and stop the fan as the hose is pulled down for use or retracted for storage.

The ES-90 also includes an alarm output, which can be used for status output to an onsite control system (by others). A built-in delay off function will ensure that the fan continues to run for some time after the vehicle has been disconnected, this ensures all of the toxic gases in the duct system will be exhausted out of the ducting before the fan stops. The delay off time can easily be adjusted between 4 seconds and 240 seconds.

Options and Accessories

 N/A The MSR-24/2 is a single throw double pole micro switch that is installed on the exhaust hose reel. When the hose is lowered the MSR-24/2 will activate the ES-90 and turn the fan on. Auxiliary contact can be used to control an automatic damper.

The BRC-MS is a single throw double pole micro switch that attaches to the BRC-450 spring balancer on fixed and boom extractors. When the hose is pulled down to connect to the vehicle, the BRC-MS will activate the ES-90 and turn the fan on. Auxiliary contact can be used to control an automatic damper.

Product Combinations

 N/A The ES-90 control box is designed in conjunction with Plymovent vehicle exhaust extraction system components including Plymovent exhaust fans, spring and motorized hose reels, fixed exhaust extractors and booms specifically for vehicle exhaust applications.

Transport of The Unit

 N/A The ES-90 control box is delivered as self-contained exhaust system controller, complete with functions for manual run and automatic start with delay off and stop.
The manufacturer cannot be held liable for any damage to the unit due to shipping or mishandling. Always handle the unit and the accompanying options and/or accessories, if any, with care.

Operations

 N/A

The controller can be set for both manual or automatic control of the fan. Depending on the exhaust extraction system, different switches are available for starting the system. Mainly two types of switches will be used:
(1) The MSR-24/2 micro switch installed on the hose reel to detect when the hose is being lowered to connect to a vehicle the MSR-24/2 will activate the ES-90 and turn the fan on. A built in “after running time” function will ensure that toxic gases in the duct system will be exhausted out of the ducting before the fan stops.
(2) The BRC-MS micro switch that attaches to the BRC-450 spring balancer on fixed and boom extractors. When the hose is pulled down to connect to the vehicle the BRC-MS will activate the ES-90 and turn the fan on. A built in “after running time” function will ensure that toxic gases in the duct system will be exhausted out of the ducting before the fan stops.
When the control unit is set into “automatic” position, the exhaust fan is started by a signal from an externally mounted micro switch. When the manual position is used the exhaust fan will run continuously until the stop button is pressed, shutting the fan down and leaving it off.

Automatic Mode:-
This mode of operation allows for automatic starting of the exhaust fan using one of the optional micro switches. When the exhaust hose is lowered or pulled down, the micro switch closes. This completes the circuit to the control box causing the fan to turn on. When the hose is retracted or raised the micro switch opens and the control box enters into a delay off mode. Once the timer has completed its (adjustable) time delay, the fan stops after the preset run time is up.
MSR-24/2:
Optional MSR-24/2 is a single throw double pole micro switch that is installed on the exhaust hose reel. When the hose is lowered the MSR-24/2 will activate the ES-90 and turn the fan on. Auxiliary contact can be used to control an automatic damper.
BRC-MS:
Optional BRC-MS is a single throw double pole micro switch that attaches to the BRC-450 spring balancer on fixed and boom extractors. When the hose is pulled down to connect to the vehicle, the BRC-MS will activate the ES-90 and turn the fan on. Auxiliary contact can be used to control an automatic damper.

Manual Mode:-
When the control box is set to the Manual Run Mode, the exhaust fan will run continuously. To exit Manual Run Mode, press the STOP button. The system will shut down and stay off. The ES-90 control box must be put back in Auto or Manual mode for exhaust fan to start.
Stop Mode:-
When pressing the stop button, the fan will stop immediately.
