4 Viscomaster Operation
Default values
Default values for your meter are configured at the factory. The specific values are determined by the options
that were specified on the purchase order. These are provided on the configuration sheet that was shipped with
your meter.
4.1 Putting into Operation
The transmitter must be powered up for all configuration and commissioning tasks, or for process measurement.
1. Ensure that all transmitter and sensor covers and seals are closed.
WARNING!
To prevent ignition of flammable or combustible atmospheres, ensure that
all covers and seals are tightly closed. For hazardous area installations,
applying power while housing covers are removed or loose can cause an
explosion.
2. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. During this period, Alert 009 is active. The
diagnostic routines should complete in approximately 30 seconds.
Post requisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics can take up to
10 minutes to reach thermal equilibrium. Therefore, if this is the initial startup, or if power has been off long
enough to allow components to reach ambient temperature, allow the electronics to warm up for approximately
10 minutes before relying on process measurements. During this warm-up period, you may observe minor
measurement instability or inaccuracy.
4.2 Check meter status
Check the meter for any error conditions that require user action or that affect measurement accuracy.
1. Wait approximately 10 seconds for the power-up sequence to complete. Immediately after power-up,
the transmitter runs through diagnostic routines and checks for error conditions. During the power-up
sequence, Alert A009 is active. This alert should clear automatically when the power-up sequence is
complete.
2. Check the status LED on the transmitter.
