DPM series Mass Flow Meters are equipped with dual color LED which allows
signaling a variety of different events with combinations of three colors (red,
green and amber) and a specific time pattern. Status LED operation can be
adjusted/ filtered for the indication of different events based on custom user
needs.
Status LED can be set to the following modes ( see Figure 13 ):
1. Normal, which supports the following events:
1.1 Auto Zero Failure (constant RED)
1.2 Fatal Error (constant RED, requiring the system to be reset for recovery)
1.3 User entry via side Push Button (specific pattern limited by a time interval
up to 35 seconds)
1.4 Power Up Sensor Warm Up interval (1 to 3 seconds). (Constant
AMBER). This can be interrupted only by User PB entry or Fatal Error.
2. Monitoring Flow Alarm and Flow Totalizer events (default settings):
2.1 High Flow Alarm RED/OFF (alternating every second)
2.2 Low Flow Alarm GREEN/OFF (alternating every second)
2.3 Totalizer#1 Event AMBER/OFF (alternating every second)
2.4 Totalizer#2 Event AMBER/OFF (alternating every second)
2.5 High Flow Alarm and Totalizer#1 Event RED/AMBER (alternating every
second)
2.6 High Flow Alarm and Totalizer#2 Event RED/AMBER (alternating every
2 seconds)
2.7 Low Flow Alarm and Totalizer#1 Event GREEN/AMBER (alternating
every second)
2.8 Low Flow Alarm and Totalizer#2 Event GREEN/AMBER (alternating
every 2 seconds)
2.9 Both Totalizer#1 and Totalizer#2 Events AMBER/OFF (on for 3 seconds,
off for 1 second)
2.10 High Flow Alarm and Totalizer#1 & #2 Events AMBER/RED (AMBER
for 3 seconds, RED for 1 second)
2.11 Low Flow Alarm and Totalizer#1 & #2 Events AMBER/GREEN (AMBER
for 3 seconds, GREEN for 1 second)
CAUTION: When “Analog Output Test” is selected, the output
reading does not represent any actual Process Information (PI)
variable (flow rate reading).
