FIGURE 4–2: Setpoints Page 1 – PQM Setup \ Preferences
• DEFAULT MESSAGE TIME: Up to 10 default messages can be selected to automatically
scan sequentially when the PQM is left unattended. If no keys are pressed for the
default message time set with this setpoint, then the currently displayed message is
automatically overwritten by the first default message. After 3 seconds, the next
default message in the sequence displays if more than one is selected. Alarm
messages always override the default message display. Note that any setpoint or
measured value can be selected as a default message.
• DEFAULT MESSAGE BRIGHTNESS: The brightness of the displayed messages can be
varied with this setpoint. This brightness will be used when the default messages are
being displayed. The brightness defaults back to 100% when:
• an alarm is present
• any one of the keys on the PQM keypad is pressed
• the PQM is turned off and on
• a text display message is sent through the serial port.
When
DEFAULT MESSAGE TIME is set to OFF, the brightness adjusts to the
programmed level after 5 minutes have elapsed, since the PQM keys were last pressed
assuming no alarm is present. If no default messages are programmed, the currently
message remains displayed and the display brightness adjusts to the programmed
level after the programmed time in the
DEFAULT MESSAGE TIME setpoint has
elapsed.
