Introduction
Scope of Manual
This manual provides installation, startup,
calibration, maintenance, and parts ordering
information for 2506 Series Multi-TrolR
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 Dcarefully 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:
DProportional-only control: Type 2506 (with snap
action: Type 2506S)
DProportional-plus-reset control (Type 2516)
DProportional-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.

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.

Connections
WARNING
The controller is capable of providing
full supply pressure to connected
equipment. To avoid personal injury or
property damage caused by parts
bursting from system overpressure,
make sure the supply pressure never
exceeds the maximum safe working
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
subsection below.
Supply Connection
WARNING
Severe personal injury or property
damage may occur if the instrument
air supply is not clean, dry and oil free
or non-corrosive gas. While use and

microns in diameter will suffice in
most applications, check with a Fisher
Field office and Industry Instrument air
quality standards for use with
corrosive gas or if you are unsure
about the proper amount or method of
air filtration or filter maintenance.
If the existing supply is corrosive,
make sure the tubing and instrument
components that contact the corrosive
medium are of suitable
corrosion-resistant materials, or
change to a noncorrosive supply
medium.
WARNING
Personal injury or property damage
may occur from bursting parts due to
overpressuring any system
component. To avoid injury or
damage, provide pressure-relieving or
pressure-limiting devices if supply or
input pressure could exceed the
maximum allowable pressures listed in
table 3.
It is recommended that supply pressure pass
through a filter/regulator combination such as a
67CFR. See table 3 for recommended supply
pressures to the receiver/controller.
Typical supply pressure for the 67CFR is clean dry
air or a gas at a pressure of 2.5 bar (35 psig) to a
maximum of 17 bar (250 psig). For specific regulator
limits, see the appropriate regulator instruction
manual.
Output Connections
See figure 3.
Use 3/8-inch tubing between the actuator and the
receiver/controller. Connect the output (diaphragm)
connection to the appropriate actuator connection.

Vents
WARNING
If a flammable or hazardous gas is
used as supply pressure medium,
personal injury or property damage
could result from fire or explosion
caused by the accumulated gas. Injury
or property damage could also result
from contact with the flammable or
hazardous gas.
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. However, a remote
vent line cannot be relied upon to
remove all hazardous gas. Vent line
piping should comply with local and
regional codes and should be as short
as possible. Select vent line piping
with adequate inside diameter and
install with few bends to reduce case
pressure buildup.
