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 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, snap-on air

connectors, a .007 in. orifice

jumper, an additional set point

dial sticker marked with 50

graduations, and a yellow remote

indication set point dial sticker.

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.

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 convenient and quicker calibration procedure.

3. 4. Start up the system to be controlled. After a reasonable period of time, the receiver-controller should be in control within the throttling range of the controlled device. by small increments until the system becomes unstable and begins to cycle. Decrease the gain setting slightly to remove the cycling effect. Doing so will provide maximum controllability with a minimum of offset. Proceed to the Gain Adjustment section.

normal proportional plus integral control of the system at all times, provided that the P/PI jumper is connected. Set Point Adjustment To make adjustments to the set point, proceed a follows: 1. Pull the P/PI jumper off of its spigot so that the receiver-controller will operate as a proportionalonly controller (no integral function). 2. Consult the system drawing to determine the required set point value. Convert this value to the pressure equivalent; see example highlighted in Fig.

deviates from the set point. (Remember when the system is off, the receiver-controller returns to proportional-only control. This feature eliminates integral windup during off periods.) Restart the system and observe to see how well it comes into control. When the system is started and the fan signal is increased to maximum (20 PSIG), the proportionalonly controller returns to proportional plus integral control to cause the control point to equal the set point.
