The following task can be performed by the fitter:

13. Connect the tubing from the air velocity sensor

pickups to the HI and LO ports outside of the

enclosure. The supply pickup goes to the supply

AVS ports, and the exhaust pickup goes to the

exhaust AVS ports on the side of the enclosure.

Make sure that the "HI" and the "LO" pressure

sides of the sensors are connected to the "HI"

and "LO" sensor ports on the controller

(Figure 1) or Autozero Modules (Figure 2). Refer

to Table 2 for air velocity sensor connections.

The installation is complete.

Replacement Instructions

CAUTION:

Replacement of a TEC requires you

to record, re-enter, or update the

initial point values of the controller

you are replacing. These are the

points marked with an asterisk (*)

on the Controller Interface Software

(CIS) display.

NOTE: CIS Rev. 2.0 or later is required for controller

replacement.

The following tasks can be performed by the system

specialist:

1. Place the ESD wrist strap on your wrist and

attach it to a good earth ground.

2. Before disconnecting the old controller, do one

of the following:

NOTE: If the new controller has a newer

firmware revision than the old controller, then

skip to the third bullet.

If the old controller communicates with the

field panel, then update the controller initial

values at the field panel.

If the old controller does not communicate

with the field panel, but communicates with

the CIS, or if the controller is stand-alone,

then record the initial values (those marked

with an asterisk (*) on the CIS display).

Record the values.

Siemens Industry, Inc.

If the old controller is not communicating at

all, or if the controller you are installing has a

newer firmware revision than the old

controller, then while at the field panel,

follow these steps:

a. Obtain a field panel Point Definition

Report for the LCTLR point. Record the

values.

b. View the initial value block. (This

information is valid only since the last

update was made). Record the values.

c. Delete the LCTLR point from the field

panel.

3. Replace the old controller as follows:

The following tasks can be performed by the

electrician:

a. Remove power from the controller.

b. If the old controller has the RTS plug

between the LAN trunk and point

terminations, then disconnect the wires

from the power trunk terminal block. If the

old controller has the RTS plug on the

opposite end of the board from the power

trunk terminal block, then remove the

power trunk terminal block.

c. Remove, in the following order, the

controller's:

LAN trunk terminal block

DO8, AI3, and DI2 only

room temperature sensor

d. Loosen, but do not remove, the mounting

screws.

e. Lift and remove the old enclosure.

Mount the new enclosure on the mounting

screws and tighten them down with either

the drill or hex nut driver.

g. Remove the appropriate knockouts.

h. If the old controller has the RTS plug

between the LAN trunk and point

terminations, then remove all terminal

blocks (except the power trunk) from the

new controller. If the old controller has the

RTS plug on the opposite end of the board

from the power trunk terminal block, then

remove all terminal blocks.
