8.2.2.5 Power Management Screen
The Remote Display has the ability to monitor the voltage from the internal power supply, and an auxiliary
24VDC input voltage to the controller. The Power Management screen provides a digital display of the
voltages applied. If an auxiliary 24VDC is not connected to the controller the voltage displayed will be correct
for the primary, and the secondary will display 0.00. If an external power source is connected to the auxiliary
24VDC input, the secondary will display the applied voltage. The power management on the Remote Display
operates just as the Power Management does on the MCX-32 controller.
Refer to Section 6.3.9 Power
Management Screen for setup operation of the Power Management.
8.2.2.6 Auxiliary Relays
The Auxiliary Relay screen allows the setup of the Remote Displays Fault and NO-Comm Relays. These
relays operate via communication with the MCX-32 controller, but may be programmed to react differently
from those in the MCX-32 controller.
The screen is the same as the MCX-32 Auxiliary Relay Screen.
Connection to these relays is obtained on the Interface PCA.
These relays may be setup as Energized or De-energized, Silence or Non Silence, and Latched or Unlatched.
Refer to 6.3.2 for the setup of these relays.
8.3 Remote Setup
The setup of the Remote Display is critical for proper operation. The setup must match the setup in the MCX-
32 Controller for proper operation. Two basic areas need to be configured:
The number of sensors must be entered on the remote displays Set # of Channels screen. This number
should match the total number of sensors connected to the MCX-32 controller.
All of the Channel Details screens must be manually configured to match the controller and the sensors
connected.
8.3.1
Sensor Channel Setup
When a sensor is being added to the controller, information for that sensor will need to be added or modified
on the Channel Details screen on the remote display. The Channel Details screen is used to view or change
information directly related to the sensor.
The Channel Details screen displays the sensor’s description,
current concentration, the current sensor condition, the range of the sensor, the gas type, sensor type and if the
channel is on or off. The Channel Details screen on the remote display will initially have default values for a
channel that has been added to the controller. These fields must be changed to reflect the same information as
those set in the controller. The fields are: Channel Description, Range, Gas Type, and Sensor Type. The
information in these fields should match the channel details information obtained from the controller. The
procedure for setting the information in these fields is the same as setting the information in the controller.
Refer to Section 6.2.
If a channel is off, this screen will display as mostly blank with the gas type, and channel being annotated as
‘OFF”.
