5.1. Calibration and adjustment
The system WinPro
®
/ MX62 provides three different methods of calibration
that depend on the detector to be calibrated as well as the prevailing conditions
on site.
5.1.1. Direct calibration at the detector
DetectorsTransmitters with a standardized output of 4-20 mA are directly
adjusted with, for example, the aid of potentiometers fitted inside the
detectors.
This calibration is carried out with the function for calibration of the
service mode to avoid triggering of relays.
5.1.2. Remote calibration for standard detectors
It is possible to adjust standard 4-20 mA detectors without actually
accessing the detectors directly.
This remote calibration can be carried out in the service mode PC
communication by adjusting the 4-20 mA output of the WinPro
®
/ MX62
within a preset range by means of special software
RemoteCalibrationPro .
ATTENTION!
Since evaluation of the 4-20 mA input signal is altered, the signal of 4-20 mA
needs to be reset in case the detector is replaced or directly calibrated. This is
achieved by the function
Calibration of the service mode.
5.1.3. Manual and automatic field adjustment of digital detectors
The digital detectors of WINTER, e.g. TBGW EX, have a 4-20 mA
analog as well as a RS485 connection to the WinPro
®
/ MX62. The latter
serves for transmission of additional data during normal operation as well
as for adjustment.
Adjustment is detailed in the operation manuals for digital detectors and
carried out with the help of software
ConfigEx .
