ABB 266 - Initialization; Factory Settings

2600T Series Pressure transmitters | OI/266/FF/ADD-EN Rev. B 87
Initialization
The 266 PdP implements up to three Analog Input Blocks, 2 of Enhanced category and 1 Standard. Each AI produce in output one
variable (AIx_OUT) suitable to be linked to other downstream function blocks. The three AIs receive in input one of the variables
produced by the Pressure Transducer Block depending by their own AIx_CHANNEL setting.
The default AIx_CHANNEL setting is:
– The Analog Input 1 receives in input the PRTB_PRIMARY_VALUE (Process Pressure) through the AI1_CHANNEL = 1.
– The Analog Input 2 receives in input the PRTB_TERTIARY_VALUE (Static Pressure) through the AI2_CHANNEL = 3.
– The Analog Input 3 receives in input the PRTB_SECONDARY_VALUE (Sensor Temperature) through the AI3_CHANNEL = 2.
Hovewer all the 3 AIx_CHANNEL can be switched to receive in input up to different 4 PRTB variables:
AI CHANNEL Variables PRTB_Variable

Pressure Process Value PRIMARY_VALUE
2
Sensor Temperature SECONDARY_VALUE
3
Static Pressure TERTIARY_VALUE
4
Scaled Process Value QUATERNARY_VALUE
Factory settings
Transmitters are calibrated at the factory to the customer’s specified measuring range. The calibrated range and tag number are
provided on the name plate. If this data has not been specified, the transmitter will be delivered with the following configuration:
