To verify each output's operation, lock the

output to a known condition using the

Function Block's Properties page in WebCTRL

or the Parameter page in SuperVision, then

make sure the equipment operates as

specified.

Analog Output Wiring

The U141v+ has one analog output that

supports voltage devices from 0 to 10VDC

(see Figure 13). The device being controlled

must have a minimum of 2000 Ohms

resistance measured from its input to ground

and must share the same ground as the

module.

Be sure the U141v+'s power is off before

wiring any inputs or outputs. Connect the

output wiring to the screw terminals on the

module.

To verify each output's operation, lock the

output to a known condition on the Function

Block's Properties page in WebCTRL or the

Parameter page in SuperVision, then make

sure the equipment operates as specified.

Using Flow Sensors

The U141v+ controls air flow in the zone

using:

• the built-in actuator and flow sensor

You must indicate Configuration 1 for the flow

control on the UNI module driver's Parameter

page. Refer to the UNI/30 or UNI/59 Technical

Instructions for details.

To connect the sensor, make sure the

U141v+'s power is off first. Attach the total or

0 to 10V

high pressure line from the VAV box to the

module's HI side, and attach the static

pressure line to the module's LO side. To

ensure an accurate reading from the flow

sensor, use the Airflow microblock in the

module's GFB. You must calibrate this

microblock using the instructions on the FB's

Properties page in WebCTRL or Parameter

page in SuperVision. Refer to the Eikon for

WebCTRL Microblock Reference Guide or the

Eikon Microblock Reference Guide for more

information.

Writing GFBs for the U1 41v+

Depending on whether you are using a

WebCTRL or a SuperVision system, you must

use either Eikon for WebCTRL or Eikon 3.0a

or later to create GFBs for the U141v+. Be sure

to enable the Zone GFB option in Eikon when

making the GFB.

A sample U-Line GFB is available at

Automated Logic Corporation's web site

(http://www.automatedlogic.com). Use this

sample as a guideline for creating your own

GFBs. A default algorithm can be loaded into

the U-card to provide stand-alone control

functions if communications between the U-

card and the UNI are disrupted. Refer to the

appropriate UNI module driver technical

instruction for instructions on setting up this

default algorithm. The U141v+'s Graphic

Function Block is stored in the UNI module,

which must use one of the following module

drivers:

• For WebCTRL systems, the DRV_UNI16

or DRV_UNI32 module driver.

• For SuperVision systems, the U1M,

U3M, UNM, or U5M module driver. A

sample GFB is also shown in Figure 14

on page 12.

When using a LogiStat sensor with the

U141v+, include a LogiStat microblock and a

Zone Control microblock in the module's
