Progressive Industries, Inc. Electrical Management System Operating Instructions for: Model EMS-PT30C Rated at 120V/30A Manufactured by: Progressive Industries, Inc. 414B Airport Boulevard Morrisville, NC 27560 (919) 462-8280 www.progressiveindustries.net Proudly manufactured in the U.S.A.
Features High/Low Voltage Protection Whenever AC power falls below 104 volts, or rises above 132 volts, the EMS automatically shuts down power to the RV. The EMS will monitor the power and once the AC power rises above 104 volts, or drops below the 132 volt level, the time delay indicator flashes for the preset time and then automatically restores power to the RV. Time Delay for A/C Compressor If AC power is interrupted, or the EMS detects a fault condition, the built in time delay is activated.
Warnings • Do not exceed the rating on the EMS for any reason, however these devices are designed to be reduced down to 120V/15A, and still maintain full protection. • Do not modify the EMS in any way, this will void the warranty, compromise protection, and could result in possible shock, and/or a fire hazard. • It is important to always check the pedestal power outlet for charring; this condition means that the AC receptacle is providing a weak connection.
Operating Instructions 1. 2. 3. 4. 5. 6. Plug into AC power. Digital display will read 888 for one second then begin scrolling the voltage, amps, line frequency, and error code(s). In addition, the time delay light will flash in the bottom right corner of the display. The EMS will read a 3-digit number which is your line voltage. Next, it will give you a “0A” reading. This is the amp reading; however, it will read zero until the time delay is complete. Then you will notice a number between 0 and 30.
