Sensyflow FMT200-ECO2 THERMAL MASS FLOWMETER | OI/FMT200-ECO2-EN REV. H
... 5 Installation
... Parameterize
The configuration box is available as an option. It is used to
simplify wiring for testing and configuration purposes. The
electric system is largely based around a star hub, which
distributes the signals from the 8-wire connection cable of the
device to the different input and output
contacts.
Power supply
The 24 V DC voltage is connected via a '5.5 mm external / 2 mm
internal' jack plug. Polarity is irrelevant, as the configuration box
features protection against polarity reversal.
LED
The LED signals green when a power supply is connected.
Analog output
The analog signal can be tapped at these terminals. The analog
signal represents the current measured value. It can be a 0 (4) ...
20 mA current signal (I) or a 0 ... 5 (10) V voltage signal (U).
Digital output
The BNC female connector is used to tap the 24 V digital signal.
Depending on the parameterization, this can be a frequency
signal, counter pulse, or a logical min. / max.signal.
Connector for Sensyflow FMT200-ECO2
This female connector is used to connect the device via the
connection cable included in the scope of delivery of the
parameterization box.
Serial interface
This enables a PC or laptop COM x interface to be connected to
the parameterization box via a commercially available serial
cable.
The configuration program can be used to customize measuring
ranges and output signals in line with requirements.
6 Commissioning
Checks prior to commissioning
The following points must be checked before commissioning the
device:
Correct wiring in accordance with Electrical connections
•
on page 10.
•
The ambient conditions must comply with the
requirements in Ambient conditions on page 9.
•
The power supply must meet the requirements set out on
the name plate.
Switching on the power supply
1. Switch on the power supply.
•
The status LED blinks red during the initialization phase
(approx. 30 s).
•
After the initialization phase, the status LED lights up in a
continuous green color.
2. Perform parameterization of the flowmeter (see
Parameterize on page 11).
The flowmeter is now ready for operation.
Inspection after power-up of the power supply
The following points must be checked after commissioning the
device:
•
Parameter configuration must correspond to the
operating conditions.
Status LED on the transmitter
The status LED on the transmitter indicates the operating
condition of the device and displays possible faults.
LED
Description
Continuous green light
The sensor is ready for operation.
Green flashing
The measuring range set has been up-scaled.
Continuous red light
Parameter or hardware fault on the sensor.
•
Reestablish parameterization, see Reestablish
the parameterization on page 15.
•
Repairs required, contact ABB Service.
Red blinking
Initialization phase of the device.
(approx. 30 s after power-up of the power supply
or after parameter changes)
Red slowly blinking
Undervoltage.
Check the supply power
Red quickly blinking
EEPROM fault.
Repairs required, contact ABB Service.
