8.4 - COMMUNICATIONS SUBMENU
The details of the communications features are discussed in
the COMMUNICATIONS Chapter (page 51).
The Communications Submenu is used to select the phone
numbers to report alarm conditions and to enter the
identification number for voice telephone reporting.
8.4.1 - Phone Numbers
Up to six (6) different phone numbers can be entered for
automatic calling in case of an alarm condition. Each number
is called sequentially until one of the numbers is answered and
the proper password is entered.
To delete a number, replace it with 0.
8.4.2 - Unit Identification
The unit identification number is used to identify individual
controllers in multiple unit facilities that are connected to the
same phone line. The default value is 1.
It should be set correctly for each controller to be able to be
accessed individually in remote multiplex operation.
8.4.3 - Alarm Calling
Select YES if you want the controller to dial automatically the
phone numbers listed in Submenu 8.4.1 or NO to disable it.
8.4.4 - 4-20 mA Output
The 4-20 mA output is an option (OPTION 4-20) to convert
sensor readings and/or control outputs into analog signals that
can be fed into analog monitoring or control equipment.
The 4-20 mA power outputs can be used for electronic pumps
or valves with analog control circuitry.
The option includes one or two identical converter boards that
plug into separate areas of the mother board of the controller
(see Chapter IV - INSTALLATION).
The 4-20 mA Output Submenu is used to set the lower and
upper limits for data conversion for each of the functions
shown on the screen (Submenus 8.4.4 and 8.4.4.1).
The standard (default) values for the 4-20 mA limits are the
values that have been selected for the out-of-range limits. This
means that the lower out-of-range limit corresponds to the
minimum signal of 4 mA and the higher limit to 20 mA.
To change the limit values of one of the functions, highlight the
desired function in Submenu 8.4.4 with the UP or DOWN
ARROW key and press the RIGHT ARROW key to access
the 4-20 mA LIMITS screen, as shown on the Submenu 8.4.4.1
for ORP.
