    If the receiver/controller is ordered separately for use with a 2500 controller/transmitter, it may not have the required mounting parts. If mounting parts are required, consult the parts list under the specific mounting application. See figure 9 for key number locations. Figure 9.

The case and cover assembly does not form a gas‐tight seal and flammable or hazardous gas could leak from this unit. Therefore, if the receiver/controller unit is enclosed, install a remote vent line to remove part of the exhaust gas to a properly ventilated area.

    2. Turn on the supply pressure to the receiver/controller. D To make the proper level or output pressure setting for a 2506 receiver/controller, go to step 3. To make the proper level or output pressure setting for a 2516 receiver/controller, go to step 9.

  • Page 15: Remote Set Point Adjustment

    Instruction Manual 2506/2516 Receiver/Controller D200129X012 June 2017 To lower level or decrease density, rotate the knob in the opposite direction. The INCREASE OUTPUT PRESSURE or RAISE LEVEL dial is graduated (in percent) to show approximate indications of the receiver/controller set point. When making adjustments, do not rely only on the dial setting.

  • Page 16: Calibration

    One way to obtain an open loop is to disconnect the controller output signal line and install a pressure gauge. Note When calibrating a combined controller arrangement such as the 2500 with the 2506 or 2516 (figure 9), calibrate the 2500 controller/ transmitter first. For a direct action receiver/controller: 1.

  • Page 17: Principle Of Operation

    Principle of Operation The 2506/2516 uses a basic pressure balance relay system. The relay is connected so that supply pressure is fed to the inlet side of the relay valve and the fixed restriction. From this restriction, the air pressure bleeds into the relay chamber on one side of the large diaphragm and also to the nozzle.

  • Page 18: 2516, 2516F Receiver/Controllers

    The action of a proportional‐plus‐reset controller (figure 13) is similar to that of a proportional controller except that feedback from the controller output pressure is piped to a reset bellows as well as to the proportional bellows. Figure 13. Fisher 2516 and 2516F Direct Action Receiver‐Controller Schematic TRANSMITTER INPUT...

  • Page 19: Maintenance

    Instruction Manual 2506/2516 Receiver/Controller D200129X012 June 2017 The 2516F receiver/controller also features an anti‐reset windup valve. This valve provides differential pressure relief to prevent proportional pressure from exceeding reset pressure by more than a set value. The proportional valve output pressure registers on one side of the diaphragm chamber and the reset valve output pressure registers on the other side diaphragm.

  • Page 20: Troubleshooting

    D The bellows assembly on the left provides either direct or reverse action. The receiver/controller (2506 or 2516) can be changed between direct and reverse action by repositioning the switch plate (key 132) on the left. Direct action (D) is when increasing transmitter input pressure increases receiver/controller output pressure.
