Introduction Connections
Remove the protective paper from the sticker on the front of the display (Figure 1),
press the display firmly against the inside of the window.
Enough space must be left underneath the unit to allow the power lead and the
RS-485 cable to be connected, approximately 70 mm.
In case of Automatic Mode installation, the push button can be removed but it is
important to complete the DIS-51 configuration before removing the button and
attaching the display to the glass of the window.
The DIS-51 and installation kit (including junction box
and push-button switch) are not intrinsically safe and
must not be located in areas what may contain explosive
or inflammable concentration of petroleum vapor.
Once installed avoid getting window cleaning agents, water, etc. onto the DIS-51
display.
Connections
The cable that comes with the DIS-51 is two meters long with 7 pole connections.
The signals on this wire are shown in the Table 1 below.
The wire connectors are used to connect the wires to the power supply, push-
button switch, and cable coming from the TLS console. These connections are
done inside the junction box (see Figure 2).
Wiring Connections
The junction box is equipped with a protection fuse. If necessary, only replace the
protection fuse with one having the same characteristics: 1A, glass 5x20mm T.
