Except for ATEX Zone 1 areas, the transmitter is available with an optional LCD. The 5-digit LCD is 
on the cover of the field wiring compartment, and indicates the mass or volume flow rate or the 
operating condition of the flowmeter. Table 8-2 explains the operating conditions indicated by the 
LCD.

The transmitter produces downscale or upscale outputs to indicate a fault.

•

Downscale: The milliamp output goes to 2 mA; the pulse output goes to 0 Hz.

•

Upscale: The milliamp output goes to 22 mA; the pulse output goes to 7200 Hz.

Unless otherwise specified on the order, jumpers are set so the transmitter generates downscale fault 
outputs. To change jumper settings for fault outputs, see Section 2.3.

Blinks ON once per second (25% ON, 75% OFF)

Normal operation

Remains ON

Startup and initialization, zero in progress, transmitter hardware 
failure

Blinks OFF once per second (75% ON, 25% OFF)

Slug flow (density below or above user-defined limits)

Blinks ON 4 times per second

Fault condition

Remains OFF

Power-supply failure, transmitter hardware failure

Power supply
• If transmitter fails to 

produce outputs, 
check for reversed 
polarity

• Make sure actual 

power supply 
matches power 
supply shown on 
label

• AC power applied to 

DC transmitter will 
damage transmitter

• Power-supply fuses 

are not replaceable
