Akytec ITP11 W Series User manual

ITP11-W
Ordering code
Functions
The ITP11 is a universally applicable digital display unit. It is designed to be connected to any device
with a 4-20 mA output (current loop).
The device has the following functions:
–Process value is displayed in accordance with the set limit values and the decimal point position
–Display range -999…9999
–Filter for damping the signal fluctuations with an adjustable time constant
–Switching between linear and square root (for specialtransmitters)
–Displaying error message when exceeding the measuring limit
–Protection against unauthorized access

Installation
1. Remove the slide covers (1) in the direction of the arrows (Fig. 2).
2. Unscrew the screws (3) and remove the front panel (2).
3. Screw the cable glands (included) with the sealing rings (5) tightly into
the enclosure, so as to guarantee the IP65 protection.
4. Not used cable entry has to be locked with the blind cap (included).
5. Feed the cable through the cable gland into the enclosure.
6. Connect the wire ends according to the wiring diagrams (Fig. 4 - 6)
and tighten the cap nut (6).
7. Put the front panel (2) back and fasten it with the screws (3).

8. To mount the device on DIN rail attach the carrier (7) to the device
using the two screws (4) and snap the device onto the DIN rail.
9. To mount the device on a tube attach the carrier (7) to the tube using
two 6 mm wide cable ties (Fig. 3), then attach the device to the carrier
(7) using the screws (4).
10. To mount the device on the wall use the two holes for the screws (4)
11. Snap the two slide covers (1) onto the front panel (2).

Polarity reversal
With particular setting parameters the device cannot actually
display the necessary 5 figures due to the restriction to four
segments.
Example
The parameters are configured as follows:
di.Lo: -999 4 mA
di.Hi: 9999 20 mA
With an input measured current of 20.8 mA the correct display
should be “10548”. Due to the restriction to four segments, the
first character is removed and the display is “0548”.
Maintenance
The maintenance includes:
–cleaning the housing and the terminals from dust, dirt and debris
–checking the fastening of the device
–checking the wiring (connecting leads, fastenings, mechanical damage)
The device should be cleaned with a damp cloth only. No abrasives or solvent-containing cleaners may be used.
