Parametrization And Calibration; Relay, Led And Display Functional Logic - ProDetec Sintrol Dumo User Manual

8 Parametrization and calibration

Dumo requires minimal set-up time to get to regular operating conditions. For trend monitoring applications,
it is enough to run the auto-setup procedure. During regular operation, the Dumo continuously measures dust
concentrations and sets an alarm signal according to the concentration and pre-set alarm levels.
The adjustment of the parameters can be done by using
 The selectable parameter sets SLOW, MEDIUM, FAST
 The local 4-Key user interface (located in the connection area)
The USB interface and Sintrol protocol for direct connection to a Windows PC. DustTool PC-Software

for parametrization and Setup comes with the instrument.
RS485 bus for

o SintrolNetwork protocol (default) to communicate with DustTool or DustLog software
o Modbus RTU to communicate with any Modbus RTU master device
RF wireless Network communication (optional) (only for SintrolNetwork protocol)

Relay, LED and Display functional logic

The Dumo has different operational statuses which are indicated to the user by changing the behavior of the
LEDs, the display or the Relays. These operational statuses are defined as follows:
NORMAL DUST LEVEL AND OPERATION: The instrument operates normally as it has been set up and

gives a valid measurement signal. The measurement signal is below the configured trash hold for the
ALERT or ALARM status.
ALERT: The instrument operates normally as it has been stetted up and gives a valid measurement

signal. The measurement signal is above the configured trash hold for the ALERT status (default 5
times the Auto setup dust level) but below the ALARM status.
 ALARM: The instrument operates normally as it has been stetted up and gives a valid measurement
signal. The measurement signal is above the configured trash hold for the ALARM status (default 20
times the Auto setup dust level).
 AUTO SETUP: The instrument gives NOT a valid measurement signal. It collects dust level data of the
present condition
FAULT, SERVICE: The instrument gives NOT a valid measurement signal. It HAS BEEN SET MANUALLY

INTO Maintenance mode or has detected a faulty behavior, detected by one of the calibration or self-
check functions
