controllers,
it
includes
two
forms
of telephone communications using touch-tone
phones:
- voice status reports,
- alarm callouts.
Voice Status Reports
The easiest way to communicate with the controller from a
remote location is with a simple touch-tone telephone.
At any time, the CHEMTROL®
CT
Controller
with the
TEL option will answer an incoming phone call. The unit will
first respond with modem tones, in an attempt to connect to a
computer. If this connection has not been established after a
few seconds, the voice announcement initiates the status
report:
" CHEMTROL® Unit __"
using the unit identification number that has been specified in
the Communications Submenu 8.3.2 (see Chapter II).
If code numbers have been specified in the Initial Setup
Submenu, the controller waits without prompting until the caller
enters his code number on the touch-tone phone. After a valid
number is entered, the unit delivers the current status report.
-
As fu
shown nction n
above, ame,
the status report includes:
-
current value,
-
applicable operating mode and
-
applicable operational status.
The status report is repeated until the caller enters a number
for a Main Menu or hangs up.
Alarm Callouts
Up to six different emergency phone numbers can be called
when an alarm condition exists. The phone numbers are
entered in the Telephone Data screen through the
Configuration/Communications Submenu 8.3.1 (see Chapter
II).
If any alarm occurs, the unit will dial in sequence the phone
numbers entered in the Communication Submenu.
After dialing the unit ID and an alarm message is repeated
verbally several times. When someone answers and enters a
valid password, the unit stops calling and deliver the alarm
message.
"Alarm Unit __"
4-20 mA SIGNAL (OPTION 420)
The 4-20 mA output is an option (OPTION 420) that includes
one or two converter boards to convert sensor readings and/or
control outputs into analog signals that can be fed into analog
monitoring equipment (BMS) or control equipment (pumps or
valves with analog control circuitry).
The converter boards plug into separate areas of the mother
board of the controller (see Chapter IV - INSTALLATION).
The four analog signals for Conductivity, pH, ORP and
temperature are set at the factory with the 4 mA and 20 mA
limits corresponding to the Low and High alarm values for each
parameter. These limits can be adjusted individually by the
operator through the controller Submenu 8.3.4 (see Chapter III
- OPERATION).
