4.1 Installation of Sensor Cartridge
The Sensor Cartridges are provided already installed to the PG2 devices and capped to protect against dirt and
damage. Replacement sensors are available individually:
•
Check gas type, range and calibration date of Sensor Cartridge.
•
Define installation place on the housing of the basic or remote sensor and break out knockouts.
•
Tighten the Sensor Cartridge with M32 hexagon lock nut.
•
Plug in the Sensor Cartridge at X2 or X3 of the sensor board. Observe plug polarity, the plug must engage.
4.2 Registration of the Sensor Cartridge
Registration and addressing of the field bus can be read in the manual for the specific PG2 transmitter or controller.
5 Calibration
The service tool STL6 or DPT6 (DGC6 EasyConf software) are available for convenient on-site calibration. See their
respective datasheet.
A sensor exchange program is also available, consult your account executive.
Prior to calibration the Sensor Cartridge must be supplied with power voltage without interruption for
warm-up and stabilization. The warm-up time depends on the sensor element and is shown in the
following tables:
