Chapter 4 – General Configuration
Firmware Version 3/4.31.37
Alarm Out provides an output signal if the meter has an active alarm. This parameter
selects the output port that will be assigned to signal an unspecified alarm condition
from the meter.
Authorized FCM provides an output signal if the meter has been authorized for flow as
a result of driver card-in or product selection.
Allows the selection of a port that will receive an input signal. The input signal will
represent the state of the meter’s permissive. If the signal is not present at
authorization or if the signal is lost during delivery, the process will be stopped and a
permissive meter level alarm will be raised.
This parameter permits the selection of a Flow Control Module (FCM) and port that
will provide an output signal. The signal will represent the loss of the meter’s
permissive.
The K-factor represents the number of pulses produced per unit of volume delivered.
The unit of volume represented in the K-factor will determine the unit of volume used
in all parameters that require a volume specification.
Quadrature Check, also known as Pulse Security, can be enabled or disabled with this
parameter. This function is intended to provide verification of meter pulse inputs by
receiving two meter pulse train inputs from a single flow meter. The quadrature input
must use Port 5. The primary meter input must use port 4.
This parameter provides a means to introduce a temperature offset to correct the
indicated temperature to correspond with the observed temperature. The offset range
can be limited from 1-5 degrees via the parameter Temperature Offset Limit.
At the default value of zero seconds, temperature alarms will be raised instantly. A
small delay can be added, in seconds, to avoid nuisance alarms that may occur when
a RTD module is synchronizing with its FCM after recovering from a power failure.
Enter the FCM # and the analog port number for the Temperature sensor.
Meter Module: <FCM Address>.A0mA
I/O Board: 00.A0mA
SCS I/O Board: 00.A0mA,00.A1mA,
01.A0mA,01.A1mA,01.A2V
You will still need to use the Temp Module Type parameter. If the Temp Module Type
is set to 0, 1, 2, or 3 then this parameter is ignored. If the Temp Module Type is set to
10, 11, or 12 then only the FCM Address is used. If the Temp Module Type is set to
13 then the FCM Address and the Port number is used.
Note: You can configure the port for 4-20mA (mA) or 1-5V (V) by pressing NEXT after
the port number has been configured. However, 1-5V is only supported on the SCS
I/O Board for 01.A2
Enable this parameter to activate a temperature sensor for this meter. Disable this
parameter if the temperature will be taken from a source outside of the SMP. See
also parameters Temp Module Type and Temp Sensor FCM#.
In the event of a RTD failure, the observed temperature can be entered manually for
use by the system until the RTD is repaired. Upon failure of a RTD, a RTD alarm will
occur. If it is necessary to take the RTD out of service, disable (turn off) the RTD
Enable parameter and key in the observed temperature. When the RTD is brought
back into service, enable the RTD Enable parameter.
