Product Usage Instructions

Installation:

At the bottom side of the EA1640 Humidity and Temperature Sensor, there are 2 magnets for easy attachment to metallic surfaces and mounting plate grooves for attaching rack mount kits.

Magnetic Mount:

1. Ensure the surface is metallic and flat.
2. Directly attach the EA1640 to the surface using the built-in magnets.

Attaching / Detaching the Rack Mount Kits:

To install rack mount kits, slide them into the mounting plate grooves until you hear a click sound. To remove them, press and hold the release buttons and pull them out.

Vertical Installation:

1. Align the rack mount kits screw holes with those of the rack.
2. Secure the EA1640 onto the rack using self-supplied screws.

Horizontal Installation:

Attach one rack mount kit to the EA1640 and secure it onto the system rack with self-supplied screws.

Keyhole (Mounting Hole) of Rack Mount Kits:

To secure the rack mount kit with screws, thread the screw through the small end of the keyhole and fasten it. For M6 screws, follow the additional steps provided.

LED:

The EA1640 Humidity and Temperature Sensor features LED illumination visible through the transparent enclosure indicating different statuses as described below:

• LED Solid: EA1640 is in working mode.
• Fast Blinking (for 2 minutes): EA1640 receives the command FindMe.
• Slow Blinking (for 10 seconds): Over-current protection (OCP) is triggered, and connected sensor(s) will power off or firmware upgrade is in progress.

FAQ:

• Q: What is the purpose of the 4-Pin Terminal Block?
  A: The 4-Pin Terminal Block is used to wire to ATEN Door Sensor (EA1440 / EA1441 / EA1442) or ATEN Capacitive Leakage Sensor (EA1540).

• Q: How do I know if the firmware upgrade of EA1640 is in progress?
  A: The LED on the EA1640 will show a slow blinking pattern for 10 seconds indicating that the firmware upgrade is in progress.

Hardware Overview

EA1640 Humidity and Temperature Sensor consists of the following components as illustrated below:

1. Signal In Port:
   Use an RJ-45 cable to connect to the sensor port of PG series PDU or the signal out port of the last EA1640.

2. Signal Out Port:
   Use an RJ-45 cable to connect to the signal in port of the next EA1640.

3. Sensor Port:
   Use an RJ-11 cable to connect to ATEN Temperature Sensor (EA1140 / EA1240 / EA1340).

4. 4-Pin Terminal Block:
   Use the sensor terminal to wire to ATEN Door Sensor (EA1440 / EA1441 / EA1442) or ATEN Capacitive Leakage Sensor (EA1540).

5. Magnets

6. Mounting Plate Grooves

7. Snap-fit

Installation

At the bottom side of the EA1640 Humidity and Temperature Sensor, there are 2 magnets for easy attachment to metallic surfaces, and the mounting plate grooves for attaching the rack mount kits.

Magnetic Mount

To mount the EA1640 Humidity and Temperature Sensor by its built-in magnets:

1. Make sure that the surface to be attached to is metallic and flat.
2. Directly attach the EA1640 to the surface.

Attaching / Detaching the Rack Mount Kits

• To install the rack mount kits to the EA1640 Humidity and Temperature Sensor, please slide the rack mount kits into the mounting plate grooves as illustrated below. A “click” sound is made once the rack mount kit is firmlyattached to the EA1640.
• To remove the rack mount kits from the EA1640, press and hold the release buttons and pull the rack mount kits out.

Vertical Installation
To mount the EA1640 Humidity and Temperature Sensor to the system rack vertically, align the rack mount kits screw holes with that of the rack, and use the self-supplied screws to secure the EA1640 onto the rack.

Horizontal Installation

• To install the EA1640 onto the system rack horizontally, you only need to attach one rack mount kit to the EA1640.
• Mount the EA1640 to the system rack, and secure it onto the rack with self-supplied screw.

Keyhole (Mounting Hole) of Rack Mount Kits
To firmly secure the rack mount kit with your self-supplied screw, please thread the screw through the small end of the keyhole (mounting hole) and then fasten the screw.

If the self-supplied screw is M6 screw, do the followings:

1. Insert the self-supplied M6 screw into the large end of the hole.
2. Move the screw toward to the small end of the hole.
3. Fasten the screw

LED
The EA1640 Humidity and Temperature Sensor is equipped with the LED illumination which is visible through the transparent enclosure. The LED illumination delivers the following status:

Fast Blinking

(for 2 minutes)

| EA1640 receives the command “FindMe”.
Slow Blinking

(for 10 seconds)

| Over-current protection (OCP) is triggered, and the

sensor(s) connected to EA1640 is going to power off.

Slow Blinking| Firmware upgrade of EA1640 is in progress.
