Figure 1 Local Display Module (LDM)
1.1.1 Graphics Display and Message Center
The graphics display shows the mode of operation, valve status, position, torque, and
alarm symbols. The message center displays actuator setup selections, data entry
feedback, and alarm messages. When no alarms are active and the valve is not moving
or is not at either limit, the message center will be blank.
1.1.2 Control Knob and Selector Knob
The control knob performs normal Open/Stop/Close function in the local control mode
and YES/NO function in the“MONITOR/SETUP”mode as detailed in Table 1.
The NO selection increments the displayed value but does not decrement.
To decrement continuously hold the NO position until the highest value is reached.
The display value will then start at the lowest value and increment from there. If the
control knob is held in the NO position for more than 2 seconds the incrementing rate
will increase from 0.5 seconds per new value to 0.1 seconds per value.

1.2 Remote Display Module (RDM)
Display Module with Bluetooth®- Model 87340
The RDM performs the same functions as the LDM.
NOTE:
If the RDM does not receive communication messages from the Central Control Module (CCM)
within 5 seconds after power is applied, the RDM will display the ashing message “CCM LINK
FAILED” and all three LEDs will blink. This will also occur if communication is lost for 5 seconds
or more.
If RDM 1 or 2 is enabled and not connected, the actuator will be in stop mode and cannot be
operated until RDM is connected or disabled.
1.2.1 RDM Operation with LDM
Two RDMs and an LDM can be connected to one actuator. The operation priority is
detailed in Table 3.
Table 3. RDM and LDM Operation Priority
