Supply Voltage and Measurement Wires
Supply Voltage: 20-72 V DC
• Allowable diameter per strand:
• inflexible wire: 0.2 - 1.5 mm
2
• sheathed flexible wire: 0.25 - 0.75 mm
2
The wire is to be connected with the correct polarization on the plus and minus
contacts of the 20-72 V DC screw clamps (
5
).
Sensor cables
• Allowable diameter per strand:
• inflexible wire: 0.14 - 1.5 mm
2
• sheathed flexible wire: 0.25 - 0.5 mm
2
• Tools required for screw clamps:
Slotted screwdriver with a 2.5 mm blade, cutting strength: 0.4 mm
• Allowable wire lengths:
• maximum 3 m for temperature, pressure and contact sensors
• maximum 3 m for monitoring station connecting wires
• If shielded wire is integrated, the shielding is to be connected to the clamp
with the grounding symbol
on it.
2-Wire Bus
A 2-wire bus enables transmission of measurement readings to the monitoring
system by the LANCIER Tx bus.
The wire is to be connected at the “a” and “b” contacts on the “Remote” wire
clamp (
6
).
Humidity Sensor
The relative humidity sensor is integrated into the device (
22
) and prewired.
Outlet Air Temperature Sensor
The exhaust air temperature sensor is integrated into the device (
22
) and
prewired.
Optional external Sensors
External contact sensor
This sensor monitors contact status (e.g. pressure switch, water level sensor,
door contact etc.). The ACS transmits contact status upon receipt of a remote
query. Any status changes that occur between remote queries are not stored in
the system memory. This means that the contact status that is to be recorded
must be longer than one monitoring system scanning period.
Connect the wire to the “Contact” screw clamp (
7
).
