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.
f.
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.
