T-5800-1 and T-5800-2
Single Input Receiver-Controllers
Installation and Calibration
The T-5800 Series Receiver-
Controllers are designed for use
with remote temperature,
humidity, or pressure transmitters
(connected to the controlled
variable “CV” input) to provide
precise control of pneumatic
devices. The T-5800-1 is a single
input proportional-only receiver-
controller with field selectable
local or remote set point. The T-
5800-2 is also a single input
receiver-controller with field
selectable local or remote set
point; however, this model
provides proportional plus integral
(PI) control. In addition, an
automatic/manual integral control

cutout feature is incorporated into
the T-5800-2 design. This Proportional Receiver-Controller PI Receiver-Controller
feature allows the system to start
up using proportional-only control
thus keeping the system from
going out of control on startup, as
is inherent to PI (automatic reset)
controllers, when the system has
been off for some time. Refer to
Product Data T-5800 for
instrument specifications and
additional details.
Installation
The T-5800 Series Receiver-
Controllers are designed for
surface mounting; refer to Fig. 3
for space requirements and
mounting details. All air line
connections are made to the units
through two snap-on input/output
connectors which have barbed
fittings for 1/4 in. O.D. polytubing.
Both single input models are
furnished with a clear cover,

Cover Removal
The cover can be removed by
applying an inward pressure to
one of the black tabs of the
receiver-controller main body to
unlatch it. The cover can also be
removed by simply taking hold of
the top and bottom sides of the
cover and pulling outward.
Oil Indicating Supply Air Filter
Check the oil indicating supply
air filter and replace as
necessary (A-4000-137 ordered
separately). When the filter is
dirty, a pressure drop will occur.
When filtering oil-contaminated
air, the filter will change from
white to red in color. If frequent
changes are necessary, check
the air supply system to
determine the cause of dirty or
oil-contaminated air.

Calibration
General Instructions
Calibration and readjustment of
the T-5800 Receiver-Controller
should only be done by a
qualified Johnson Controls
representative, equipped with the
proper tools. An X-200-173
Calibration Kit (see Fig. 6,
ordered separately) is available
for making adjustments and
pressure checks on the
T-5800. This kit provides all of
the necessary gages, regulators,
and connectors for a more Fig. 6: X-200-173 Calibration Kit

calibration procedure.
An X-200-140 Hypodermic
Needle Test Probe and
appropriate gage (see Fig. 7,
ordered separately) is also
available for troubleshooting, for
test point readings, or for final set
point adjustments under actual
job conditions. Note: Figure 8
illustrates an alternative
method of checking pressure
readings on the
T-5800 where use of a
hypodermic needle test probe
is prohibited. Fig. 7: X-200-140 Test Probe with Gage

Set Point Adjustment
To make adjustments to the set
point, proceed as follows:
1. Consult the system drawing to
determine the required set
point value. Convert this
value to the pressure
equivalent; see example
highlighted in Fig. 10 (75°F on
a 50 to 150°F range would be
a set point of 6 PSIG).
2. Take a set point pressure
reading using the appropriate
method and gage, as
illustrated in Fig. 8. Adjust the
local set point dial or the
remote adjuster (manual or
automatic) until the pressure
matches the value noted in
Step 1. Remove the pressure
reading device and reconnect
the jumper (if applicable).
