CONF - Change I/O - Short / Off Values option
(652/653 S Temperature transmitter)
The Short value and Off value procedure available for a Temperature
Transmitter model 652/653 S is used to set the test condition and the
value of mA analog output in case of short or broken condition.
Here are given the display that are used in this procedure.
Press the Key F3 (CHNG) to access the Sensor Error Configuration
display, where it is possible to select amoung:
- Test for broken
- Test for short
- Test for broken, short
- No test
The next step is to define the mA value for short and off selection.
Enter the mA value and then press ENTER key to accept and send the
new value to the transmitter.
CONF - Change I/O - Max / Min RESET option
(652/653 S Temperature transmitter)
The transmitter provide an indication for the Minimum and the Maximum
value that has been read with the correspondent units, ohm, mV, Deg. C,
etc. Press the Key F3 (RESET) to reset the Maximum and Minimum
value, to the actual reading.

CONF - General Configuration - POLLING ADDRESS SETTING
( for Multidrop operation )
For multidrop operation, each transmitter must have a unique polling
address ranging from 1 to 15 being the address 0 reserved for normal
analog output operations or non-multidrop operation.
WARNING - The setting of a polling address different than zero
FORCES THE TRANSMITTER OUTPUT IN 4 mA FIXED mode: the
transmitter transmits only digital data and can then only be used in
control systems capable of reading the process value from the
transmitter using the HART protocol. THE TRANSMITTER CANNOT
BE PART OF AN ANALOG CONTROL LOOP.
Pressing from the Configuration Main Menu the F3 key ( GEN CONF ) and
then F1 ( POLL ADDR )on the next display, a warning display informs
the user that this procedure can be used only if the connection with the
transmitter was established via the DIRECT/POLL method and not via
the BROADCAST method. Press F4 to confirm and proceed or ESCAPE
to return to the main menu. If PROCEED has been pressed the following
display appears. The actual polling address is displayed within square
brackets: using F1 or F2 keys you can select the proper polling address,
usually progressive from 1 to 15. Press F4 for ENTER: if the change is
accepted the display returns to the Configuration Main Menu otherwise
a proper message is displayed.
Important Note : Set the Polling Address to 00 ( zero ) to return the
transmitter to the normal analog output operation.
WARNING: If the transmitter is part of a Multidrop Network this
operation must not be done: the presence of a transmitter with a
polling address 00, having then the analog output ranging from 4 to
20 mA, spoils the functioning of the Multidrop Network.
