Hardware Start-up
Gas connections:
Make sure the helium cylinder is tightly secured to the wall and the regulators are tightly
mounted on the cylinder. Check the helium and Argon quality (5.0
– equivalent to Zero Grade
classification - or better). Do not connect yet the tubing to the helium inlet at the EnCal 3000.
Open carefully the helium regulator and check the helium pressure at the outlet of the regulator.
Adjust to 5.5 barg (80 psig). Purge the tubing before connecting to the EnCal 3000 for about
30s. Make the connection with inlet HE. Check for leaks.
Make sure the calibration gas cylinder is tightly secured to the wall and the regulators tightly
mounted on the cylinder. Check the calibration gas certificate. The tube should be flushed once
before it is connected to the Encal3000. Open carefully the calibration gas regulator and check
the calibration gas pressure at the outlet of the regulator. Adjust to 1-4 barg (15-57 psig). Purge
the tubing before connecting to the EnCal 3000 for about 30 seconds. After the connection a
check for leaks is required.
Check the stream gas pressure at the connection point with the EnCal 3000. Adjust to 1-4 barg
(15-57 psig). Purge the tubing before connecting to the EnCal 3000 for about 30s. Make the
connection with inlet
STR1
. Check for leaks. Repeat this procedure for the other streams if
applicable.
Do a leak test of the total system.
Power Supply cable:
Standard industrial 2-wire cable.
(The use of an external junction box is responsibility of the customer / installer)
Power rating 50 W nominal (120 W start-up peak) for non-heated version (ambient T > 0°C or
32°F).
Power rating 120 W nominal (240 W start-up peak) for heated version (ambient T < 0°C or
32°F).
For the location of the internal connector see figure 5.6.
Data communication cable:
Ethernet cable (PC and/or ModBus TCP/IP clients):
Standard straight cable, shielded twisted 4 wire cable or industrial CAT5 quality. For the location
of the Ethernet connector see figure 5.7.
Serial Modbus:
o
Standard industrial data communication cable twisted pair
3-wire for RS 485 communication
3-wire for RS 232 communication
Electrical Installation in Hazardous Areas
The start-up should be done by an experienced technician, with a proven knowledge
of electrical installations in explosion proof areas. Always remember to make sure
there is no hazardous condition present during installation. Follow the instructions
below carefully and make sure you have fulfilled all necessary safety steps before
powering up the EnCal 3000.
