2. Installation and Commissioning
PRECAUTION: Please read this manual carefully before energizing the indicator and
perform the commissioning operation according the procedure given here. Use trained
personnel for cleaning, commissioning, checking and service of the indicator. The
interference of untrained personnel may cause some unwanted damages or injures.
2.1. Mechanical Installation
First of all please determine the place where your instrument can operate safely. The
place where you will use/install your instrument should be clean, not getting direct sunlight
if possible, with a temperature between -10ºC and +40ºC, 85% maximum relative humidity
non-condensing.
The cables should be installed safely to avoid mechanical damages.
The housing dimensions are given in Section 5. To avoid electrical noise protect your
transmitter which has very low input signal level, from the equipment that produces
electrical noise.
Place your transmitter in a separate metal panel from the frequency converters and motor
contactors, or at least place it in another partition of the panel. Do not combine signal
cables and power cables in cable trays. And check that the cables are wired properly in
order to prevent mechanical damage.
2.2. Electrical Connections
The pin layout of TX 1 is shown below. Electrical connections should be done carefully.
TX 1 requires a power supply of 230 VAC, 50 Hz and 6 VA ( Figure 1 ) or 24 VDC 0.2 A
( Figure 2 ) to operate.
The meanings of the pins are:
