COMMERCIAL CONTROLS Pneumatics

Multi-Function Reset Volume Controllers • Pressure independent controllers for use with VAV terminal units • Velocity setpoint is reset between adjustable minimum and maximum limits by a master controller • Equipped with separate adjustment knobs for

• Includes mounting bracket • L40-187 is used with most all VAV units except Trane units • L40-188 is typically used with Trane VAV units Specifications: • Output sensitivity: L40-187 5 PSI/.02" w.g., L40-188 5 PSI/.04 w.g. • Main air pressure: 15 to 30 PSIG • Maximum signal pressure: 6" w.g. applied to either port (H or L) WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov

minimum and maximum airflow setting • Multi-function for direct or reverse acting thermostats, and N.O. or N.C. damper actions • Reset start point is factory set at 8 PSIG (Adjustable 0-10 PSIG) • Reset span is factory set at 5 PSIG (adjustable 0-10 PSIG)

Relays • L40-199 and L40-204 reversing relays reverse the action of a proportional control signal, with adjustable offset to advance or retard cross over on both models • L40-199 has a 9 PSIG cross-over, L40-204 has an 8 PSIG cross-over, and they are for low capacity; for high capacity requirements, use L40-205 (RCC-1502) or L40-206 (RCC-1504) • L40-200 low pressure selector selects the lowest of two pneumatic signals and can be used as a signal repeating relay • L40-201 high pressure selector selects the highest of two pneumatic signals

• L40-202 diverting relay diverts input signal to either of two outputs or selects one of two inputs for the output signal and can be used to feed or exhaust a circuit (SPDT switch action) Specifications: • Max. pressure: 30 PSIG • Mounting bracket included, can be mounted in-line • Connections: 3/16" fittings for 3/4" O.D. polyethylene tubing WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
