Installing the Optional LMi5 Interface
Accessory
The LMi5 accessory (not provided) provides the ability to monitor
up to 5 sensors around the dock door with the myQ
Management. These sensors provide the status of equipment to
the myQ Dock Management.
®
Typical sensors include:
PRE-SENSOR: This is a trailer presence sensor to provide status
of whether a trailer is present at the dock or not.
WS-SENSOR: This is a mechanical roller limit switch to
determine the status of a trailer restraint system
or position of a dock leveler (deployed or stored)
WS-SENSOR-E: This is a photoelectrical sensor to determine the
status of a trailer restraint system or position of a
dock leveler (deployed or stored)
Once the sensors are connected to the LMi5, go to
www.myQBusiness.com to set up your interface box configuration
and name the connected sensors: (Normally Open/NO or Normally
Closed/NC). The default status is Normally Open.
INSTALLATION
1. Select a convenient location within 35' (10.6 m) of the
operator to mount the LMi5 accessory.
2. Remove the 4 screws on the cover of the LMi5 and remove
the cover (Figure 1)
3. Add ½" conduit connector or cable gland (not provided)
to top and bottom holes of LMi5 per requirements of
installation.
4. Make wire connections (Figure 2) from CMD (Command)
to Terminals 2 (red) and 3 (white) on the DDO8900W.
Recommended: solid wire 14-24AWG. Route wiring through
the top of LMi5.
5. Press the SW1 button to learn the LMi5 to the operator. The
LED should remain lit once learned.
6. Make wire connections (Figure 2) from ACCY (Accessory)
inputs to the sensors. Recommended: solid wire 14-24AWG.
NOTE: Provide all required power externally – Accessory
sensors cannot be powered from the LMi5 accessory. Route
all wiring for the sensors to the center of the board and down
through the bottom of the LMi5.
7. Toggle the accessory device (switch the state of the contact).
You should see the LED on the related LMi5 input change
state in response.
8. For wire retention of the various accessories, use the cutout
near the bottom of the board (see Figure 2) in conjunction
with a cable tie (not provided) to retain the various wires
from the sensors.
9. Secure the cover with the 4 screws provided.

• Do not apply line voltage power directly
to both terminals of each LMi5 input. An
accessory must be connected as part of
the circuit.
• The LMi5 should only be connected to dry
contact switches/sensors, as it will not
operate with open collector type devices.
• You may only connect ONE LMi5 Interface
to a single dock door operator. Multiple
LMi5 units are not supported.
