Introduction
Scope of Manual
This manual provides installation, startup,
calibration, maintenance, and parts ordering
information for 2506 Series Multi-Trol
receiver/controllers. Figure 1 shows a Type 2506
receiver/controller. Figure 2 shows a Type 2516
receiver/controller.
A 2506 Series receiver/controller is often used with a
2502 Series Level-Trol® controller/transmitter. For
information about 2502 Series controller/transmitters
or associated equipment such as pressure
regulators, sensors, accessories, or related control
devices, see the appropriate instruction manual, or
contact your Fisher® sales office.
No person may install, operate, or maintain a 2506
Series Multi-Trol receiver/controller without first D
being fully trained and qualified in valve, actuator
and accessory installation, operation and
maintenance and D carefully reading and
understanding the contents of the manual. If you
have any questions about these instructions, contact
your Fisher sales office.

Description
See table 2.
The receiver/controllers described in this manual
provide:
D Proportional-only control: Type 2506 (with snap
action: Type 2506S)
D Proportional-plus-reset control (Type 2516)
D Proportional-plus-reset-plus-anti-reset windup
control (Type 2516F)
See figures 9, 10, and 11.
The receiver/controller takes a pneumatic input
signal from either a 2500 Series
controller/transmitter or a control device. The unit
then provides a pneumatic output signal that
operates a final control element.
When a Type 2506 receiver/controller is used to
provide proportional-only control, the pneumatic
output signal from the unit can also be piped to a
remote receiving indicator or recording device. This
provides a visual indication of receiver/controller
action.
The INCREASE OUTPUT PRESSURE adjustment is
used to increase or decrease the output pressure in
relationship to the input pressure. Changing this
adjustment changes the position of the nozzle in
relationship to the beam/flapper assembly. In turn,
the amount of supply pressure released by the relay
is changed and the pneumatic output signal that
operates a final control element is affected.
If a remote set point signal is used, it is piped to the
remote set point connection and into remote set
point bellows. The remote signal expands the
bellows and moves the beam/flapper assembly. This
affects the controller output in the same way a
change in the INCREASE OUTPUT PRESSURE
adjustment affects the output.

to the lower yoke boss of the actuator yoke. Be sure
the spacers support the mounting plate. Be sure the
receiver/controller is parallel with the actuator yoke
and then tighten the cap screws into the yoke boss.

See figure 4 for a typical mounting plate. Key
numbers are shown in figure 5.
1. Locate the mounting plate (key 164, figure 5).
Select appropriate mounting holes in the mounting
plate for the receiver/controller. Then, align the
mounting holes in the mounting plate with the
mounting holes in the receiver/controller case.

1. Install lock washers (key 83) on the cap screws
(key 39). Then, insert the cap screws through the
mounting plate from “back to front”. Place a spacer
(key 174) over the threads of each cap screw as it
extends from the mounting plate. The spacers are
required to properly separate the receiver/controller
from the mounting plate. Then, thread the cap
screws into the mounting holes in the
receiver/controller case and tighten.
2. Install lock washers (key 83) on the cap screws
(key 48). Then, insert the cap screws through the
mounting plate from ‘‘front to back’’. Place a spacer
(key 174) over the threads of each cap screw as it
extends from the mounting plate. The spacers are
required to properly separate the mounting plate
from the wall mounting position. Then, thread the
cap screws into holes prepared at the wall mounting
position and tighten.
3. Provide appropriate piping from the filter/regulator
output connection to the receiver/controller supply
connection.
Actuator Diaphragm Case Mounting
To mount a receiver/controller to the diaphragm
casing of a standard Fisher diaphragm actuator,
remove two hex nuts and hex head cap screws
securing the upper and lower diaphragm casings. If
necessary, refer to the appropriate actuator
instruction manual to locate the hex head cap
screws and nuts.
See figure 7 for key number locations.

receiver/controller mounting holes and tighten the
cap screws to attach the mounting plate to the back
of the receiver/controller.
3. Locate the receiver/controller mounting position
on the horizontal edge of the diaphragm case. A
typical Fisher diaphragm actuator features upper
and lower diaphragm casings held together with hex
head cap screws and hex nuts. Remove the hex
nuts from two hex head cap screws joining the upper
and lower casing. Then, remove the cap screws.
4. Place the mounting bracket over the empty
casing holes. Insert the casing cap screws through
the mounting bracket, upper casing, and lower
casing. Add the nuts and tighten to secure the
mounting bracket with receiver/controller to the
casing.
5. If supply pressure is piped through a
filter/regulator, the regulator may be attached in one
of two locations:
D Attach the regulator directly to the upper yoke
boss using the cap screws (key 85) for yoke
mounting.
D Attach the regulator to the casing using a
mounting bracket (key 177). The mounting bracket
for the regulator is the same as the mounting bracket
for the receiver/controller. Follow steps 1 through 4
to mount the regulator.

the receiver/controller. Then, align the mounting
holes in the mounting plate with the mounting holes
in the receiver/controller case.
2. Place the two cap screws (key 48) through the
mounting plate from ‘‘back to front’’. Place a spacer
(key 174) over the threads of each cap screw as it
extends from the mounting plate. The spacers are
required to properly separate the receiver/controller
from the mounting plate.
6. Provide appropriate piping from the filter/regulator
output connection to the receiver/controller supply
connection.
2500 Series Controller/Transmitter and
2506 Series Receiver/Controller
Mounting
If the controller/transmitter and receiver/controller
are ordered simultaneously, the factory will mount
them together before shipment (figure 9). For
examples of typical transmitter/receiver mounting
arrangements, see figures 10 and 11.
If the receiver/controller is ordered separately for use
with a 2500 Series 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.

pressure of any connected equipment.
To complete the installation of a receiver/controller,
make connections with tubing and fittings between
the receiver/controller and the actuator. The fittings,
tubing, and mounting parts required depend on the
type number and optional equipment such as filter,
regulator, and bypass valve.
All pressure connections on the 2506 Series
receiver/controllers are 1/4-inch NPT female fittings
(figures 3 and 9). Use 1/4-inch piping or 3/8-inch
tubing to these connections.
If remote venting is required, see the Vents
