Procedure
1. At opened door, lead the sensor cable through a cable gland close to the slot where
the CHARM to be connected is installed.
2. Strip the cable sheath at a length of approximately 200 mm.
3. Strip each wire at a length of approximately 10 mm.
4. Connect the wires to the CHARM Terminal Block.
• Connect the signal wire of the voltage signal source to terminal 1 of the CHARM
Terminal Block.
• Connect the GND of the voltage signal source to terminal 2 of the CHARM
Terminal Block.
• Connect the cable shield to a ground terminal (see Grounding).
5. Ensure that the cable gland, where the sensor cable is led through, is closed to keep
the IP protection class of the AMS Asset Monitor.
6. Continue with the installation or close the door (see Close the AMS Asset Monitor).
5.5 Install a DO 24 V DC High-Side CHARM
The DO 24 V DC High-Side CHARM is a discrete output CHARM for momentary output
signals or continuous pulse outputs. The CHARM is supplied by the AMS Asset Monitor. A
CHARM Terminal Block is required for the installation. If a relay output is required use the
CHARM Relay Output Terminal Block. See Installing CHARMs hardware for the general
CHARM installation procedure.
