Installation of Bearing Display Module BDM
1. Hold down A+B until all LEDs light up. The
display shows the active program(s).
2. Hold down A+B until the display flashes
”000”.
3. Press A for 'one channel mode'. The display
shows ”0XX”, where the flashing "XX" is the
number of the active program.
4. To change the program, press B repeatedly
until the desired program number is shown.
5. Press A to go to the reset setting. B toggles
between automatic and manual reset (see
below).
6. Press A to end the programming mode and
start normal operation.

Alarm reset
ALERT (yellow LED on) always has automatic reset: both the status display and relay positions are
controlled by the measured signal. This means that an alarm disappears when the measured value drops
to or below the alarm limit.
ALARM (red LED on) has the same automatic reset when 'AAU' is active. When manual reset 'Art' is
active, the status display and the relay positions are held until either A or B is pushed. This will reset the
status display and the relays if the alarm condition has disappeared.
Please note: if the incoming signal drops below 4 mA while ALARM is held, the red LED will flash instead
of the yellow LED.
Relay action in one channel mode
The relays are specified 24 V/100 mA. In one channel mode, the relay mode 'r 1' is active and can not be
changed by the user.

In one channel mode, the module receives the analog
signal on channel 1. Two alarm levels can be programmed
(see page 8).
Level 1 = ALERT = yellow LED is connected to Relay 1.
Relay 1 is NC = normally closed. It opens on power
failure and on alarm (value above the lower or ALERT
alarm level). Thus, it will be open when the yellow or the
red status LED is on.
Level 2 = ALARM = red LED is connected to Relay 2.
Relay 2 is NO = normally open. It closes on ALARM =
red status LED is on.

NO
