Z-2400-Sleeper Analogue Input Connections; Connecting Rtds To A Sleeper - Intech Z-2400-SLEEPER Installation Manual

Z-2400-Sleeper Analogue Input Connections:

ALWAYS program the Sleeper before connecting inputs!
Choose a node address for the Sleeper - 1~32 (can be same node number as base or remote).
Choose a sleep time for the Sleeper (1, 2, 5, 15, 30 or 60 minutes).
Connect the Sleeper to a PC using the XU-USB Programming Kit. Use the XU Setup software to select each Sleeper
input channel separately and program the inputs required (DIP switch B, 8 must be set to ON while connected).
Connect analogue input wires into the input terminals of Sleeper (refer to following diagrams).
Set DIP switch B, 8 to ON to power up Sleeper unit.
Check the Sleeper has made a connection (LEDs 1 & 2 should toggle for 5 seconds once a stable connection is made).
Remember to always reset (power off and on), the Sleeper after programming.
Note:
1. The two analogue inputs are not isolated from each other, and
care must be taken when connecting signals that are not isolated
from each other or ground.
2. Both analogue signals can share a common as per this example
4~20mA hookup:
3. If permanently powering the Z-2400-Sleeper, use only an isolated
power supply; i.e. isolated from ground and other devices. Do not
use this power supply to power external devices. If only a
common power supply is available, use the PSW isolating
power supply to power the Sleeper only, to maintain isolation.
