Technical data of product parameters

In order for EIA/TIA-485 signals to be transmitted properly, each pair must be properly terminated.
The value of the termination resistor should be equal to the impedance of the communications cable CONTEMPORARY MODHUB-16E
used. Values are typically 150 to 200Ω.
The receive lines at the converter or host device should be terminated in the converter, the
connector to the host device or the device itself. Typically the converter documentation provides
instructions for termination.
Use a terminating resistor on the receive lines on the last controller on the 485 line. Set JU1 inside CONTEMPORARY MODHUB-16E
the CLS200 in position B to connect a 200Ω resistor across the receive lines. Refer to Changing
Communications on page 153.If a process, deviation, failed or system sensor alarm occurs, the controller switches from any Single
Loop display or Bar Graph display to the Single Loop display for the loop with the alarm. The global
alarm output turns on and a two-character alarm code appears in the lower left corner of the Single CONTEMPORARY MODHUB-16E
Loop display.
If the alarm is for a failed sensor, a short message appears in place of the process variable and units.
Control outputs associated with failed sensors are set to the value of the SENSOR FAIL HT/CL
OUTPUT % parameter (default, 0%).
The alarm code blinks and displays cannot be changed until the alarm has been acknowledged.
Once the alarm is acknowledged, the alarm code stops blinking. When the condition that caused the
alarm is corrected, the alarm messages disappear. Alarms that still exist but have been acknowledged are displayed on the Bar Graph display. A letter
or symbol indicates the alarm condition. See Table 3.3 for a full list of alarm codes, failed sensor
messages and alarm symbols.
