Code No. LIT-930090

The Y350R is a rectified Class 2, 24 VAC power

supply module designed specifically for use with

System 350™ Modular Control Systems.

As with all System 350 products, the Y350R is housed

in a compact NEMA 1, high-impact plastic enclosure.

The modular design provides easy, plug-in

connections for quick installation and future

expandability.

All System 350 add-on modules snap on to a DIN rail

and plug into the control and to each other via 5-pin

connectors. Add-on modules can be arranged in any

order and there is no wiring required to interconnect

the System 350 components.

peration

The Y350R operates from 240 VAC or 120 VAC

power. A 24 VAC, Class 2, step-down transformer

brings the voltage to a level which the System 350

modules will accept. There are no adjustments for the

power module.

IMPORTANT: All Series Y350R Power Modules

are designed for use only in

conjunction with operating

controls. Where an operating

control failure would result in

personal injury and/or loss of

property, it is the responsibility of

the installer to add devices

(safety, limit controls) that protect

against, or systems (alarm,

supervisory systems) that warn

of, control failure.

nstallation and Wiring

The Y350R case has provisions for mounting to a

standard 35 mm DIN rail, or can be mounted using the

four key slot mounting holes located in the rear of the

case.

Mount System 350 modules in any convenient location

using either the DIN rail mounts or the mounting holes

located on the back of the control case. The

components are not position sensitive, but should be

mounted so they can be easily wired and adjusted.

Y350R Power Module Product/Technical Bulletin 3

IMPORTANT: All wiring must be installed to

conform to the National Electrical

Code and local regulations.

1. Secure the module to the DIN rail, wall, or panel.

WARNING:Electrical Shock Hazard.

Disconnect power supply before

modules are interconnected and

wiring connections are made to

avoid possible electrical shock or

damage to the equipment.

2. Connect input wiring to the Y350R power module.

Strip approximately 3/8 inch from the wire

insulation, insert the wire under each terminal

screw, and tighten. (See Figure 3.)

Note: If conduit is used when installing System 350

components, be sure to connect the hub to the

conduit before the hub is secured to the

enclosure.

heckout Procedure

Before applying power, make sure installation and

wiring connections are according to job specifications.

After necessary adjustments and electrical

connections have been made, put the system in

operation and observe at least three complete

operating cycles before leaving the installation.

roubleshooting

If the control system does not function properly and

the Y350R is suspect, proceed as follows:

1. Connect a Digital Voltmeter (DVM) between the

24V (+) and COM (-) terminals located on the

control module’s left-side connector. (Terminal

designations are marked on the control module.)

2. Select DC volts on the DVM and verify that the

voltage is between 16 and 38 VDC. If the DVM

reading is within range, the Y350R is functioning

properly.

Note: Consult the

Troubleshooting

section of the

appropriate control bulletin for a complete

system troubleshooting procedure.

3. If the DVM reading is not within the indicated

voltage range, check wiring and correct if

necessary. If the wiring is correct and the reading

remains out of range, replace the Y350R.

epairs and Replacement

Field repairs or calibration must not be made.

Replacement modules are available through the

nearest Johnson Controls representative. (See Table

2.)
