    IN THE EVENT OF OVERHEAT, BUT THE INTERLOCK MUST BE PROPERLY CONNECTED TO THE RF SOURCE FOR THIS FUNCTION TO OPERATE. NEVER OPERATE WITH INTERLOCK BYPASSED OR MALFUNCTIONING. TO DO SO WILL VOID THE WARRANTY. 6600/Rev/Mar.2021 Page 7 Altronic Research Inc.
  • Page 8 Do not apply more than rated power to unit. Damage will occur if large overloads are applied. CAUTION When using any cleaning solvents or solutions, assure that there is adequate ventilation to protect personnel from breathing any irritable or possibly toxic fumes. 6600/Rev/Mar.2021 Page 8 Altronic Research Inc.
  • Page 9: Introduction

    Load is correctly connected to the RF source and the transmitter alarm, operate transmitter as desired. Units purchased with fans may be operated after ascertaining that the load is connected to the correct power supply with a disconnect, connect the transmitter interlock 6600/Rev/Mar.2021 Page 9 Altronic Research Inc.

    The proper procedure to lock out and mark controls prior to allowing or commencing maintenance on the equipment; The proper procedure to obtain clearance to remove lockouts and out-of-service marks and return the equipment to normal service. 6600/Rev/Mar.2021 Page 10 Altronic Research Inc.
  • Page 11: Test Equipment And Special Tools

    While inspecting RF connector, measure DC resistance of the unit by reading from the center conductor to the outer conductor. Compare this reading to that on the specification sheet at the end of this manual. Reading should be ± 1 ohm. If not, consult factory. 6600/Rev/Mar.2021 Page 11 Altronic Research Inc.
  • Page 12: Adding Fans

    • Test for proper fan operation by jumping the terminals of either thermal switch that is wired in the fan circuit. They have a yellow dot on them. • Place the roof back on the load. 6600/Rev/Mar.2021 Page 12 Altronic Research Inc.
