2.3.2 Electric:
Work as followed when installing the enclosure:
• Remove the protection cover (B in fig.2.3b) from the cool shaft by
loosening the four bolts which hold the cover. If necessary remove
the connector and earth cable from the fan on the cover to create
more working space. Loosen the two grip nuts from the electro
front plate (A in fig.2.3b). Unplug the connectors to remove the
plate from the enclosure
• Pull the connection cable through the cable tubes which run
through the enclosure (A in fig.2.3c).
• Pull the cable through the cable glands (B in fig.2.3c) on the
separation plate between the cool shaft and electronic
compartment. Strip the cables long enough to reach the terminal.
Terminal connections
Power supply
Connect the power supply cable (230VAC/50Hz) to contacts 1 (live), 2
(null) and 3 (ground) of the terminal (see sticker in fig.2.3d).
Pulse Input
Connect the potential free pulse / batch contact to contacts 4 and 5.
(pulse input) for pulse registration and pulse proportional sampling. Be
aware: keep the pulse input frequency <1 Hz. Use a pulse length of ±100
msec.
When using the pulse input for batch control sampling, the pulse counter
in the display counts every batch contact.
Digital Input 1 & Digital Input 2
Connect a potential free contact to contact 4 & 6 (DI1) and/or
4 & 7 (DI2), check §3.5.6 to configure the inputs.
Analogue Input (current)
Connect the 4—20mA flow signal cable to terminals 8 (+) & 9 (-). Check
§3.5.5 to configure the analogue input.
Digital output 1 (2= optional)
Terminals 10 and 11 are used for the programmable digital output 1,
The relay output is normally open. Terminals 10 & 12 are used for digital
output 2. Check §3.5.6 to configure the digital output.
