6.8 Alarms and relays
connections
Cables signal section: from 0.14mm²
(26AWG) up to 1mm² (17AWG).
Maximum relay voltage and current: 30Vac
/30Vdc max, 1A.
Alarm inputs: 2 (auto-powered from 12Vdc
up to 18Vdc).
Connect the digital I/O cable to the relative
connector (J6, Fig. 11, page 13 and Fig. 11, page 13).
The maximum cable length for each alarm is 200m.
The removable connector is supplied in the kit.
CONNECTION OF THE ALARM INPUTS AND RELAYS
Terminals Description
RL1A, RL1B,
RL2A, RL2B Dry contacts of the two relays which can be
activated via alarm or by user command
AL1, AL2, COM Self-powered alarm inputs referred to the
shared terminal
Tab. 2
The device can be equipped with a washing system
as an accessory. Connect the pump activation signal
cable to the indicated relay: RL2A, RL2B.
6.9 Ethernet cable connection
Use of Ethernet cables with the following
characteristics is highly recommended:
• Minimum cabling type: Class D (ISO/
IEC11801:1995) or Category 5 (ANSI/EIA/TIA-
568-A:1995).
• Shielded twisted cable (STP).
• 4 pair.
• Maximum DC Loop Resistance: 25Ohm.
Connect the ethernet cable to the relative connector
(J3, Fig. 11, page 13).
If the product is powered by 90W PoE, the ground
cable must be connected to the relevant terminal
(GND_EXT, Fig. 11, page 13).
6.10 Installation of the upper
body
Installation of the upper body must take
place with the base not powered.
Check the LED indicated in the figure is off (Fig. 12,
page 13).
Check the gasket on the base is in good condition
and positioned correctly (Fig. 13, page 13).
Place the unit body on the base aligning the
reference marks. Be especially careful not to damage
internal components during installation (Fig. 14,
page 14).
To avoid scratching the product with the hexagonal
wrench, align the groove on the body of the product
with the screw before screwing it in (Fig. 15, page
14).
Fasten the upper unit to the base using the 3 fixing
screws (Fig. 16, page 14).
Pay attention to the fixing. Tightening
torque: 4.5Nm (±0.2Nm).
Apply thread-locker into the holes for
screws (Loctite 222®).
