If installing RL-4 modules for the RD-64X, they will need to be mounted in a separate enclosure. For the
N4X enclosure, wire the power and Modbus™ from the first RL-4 module to the DIN rail mounted
terminal block in the RD-64X-N4X labeled “RS-485 MASTER” and “VDC Out” (See Figure 3). For the
N7 enclosure, wire the power and Modbus™ from the RL-4 module to the OUT connector of the transient
protection module per Figure 9. If using the AC/DC converter option, wire only the Modbus™ from the
first RL-4 module to the J1 connector per Figure 10. The RL-4 modules will need to be powered separately
using this configuration. An RL-4 module connected properly to the remote display will have a flashing
DATA COMM LED to indicate a valid communication status and will provide a relay output. If an RL4
module is connected, it must be set up accordingly (See section 7.3).
NOTE: RL-4 modules must be connected accordingly to the remote display, they must be
addressed correctly and only those RL-4’s associated with a channel will be available.
After identifying the correct address for the RL-4 module, the alarms to be used need to be defined and
configured via the operator interface in section 7 System Operation and Configuration. A properly
addressed RL-4 that is correctly connected and configured to the remote display will respond to channel
activation with an alarm output related to the alarm set points of the associated channel. If the remote
display does not detect an RL-4 module, the blue LED (Fault) will start flashing. Go to the FLASHING
BLUE LED CODES menu to identify the problem (See section 7.3.10).
Each relay within the bank can be set as Energized/De-Energized, Silenceable/Non-Silenceable, and
Latching/Non-Latching (See section 7.3.9).
4.1.1 Energized or De-Energized
All alarms relays - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured to operate in either energized
or de-energized mode. In de-energized mode, the normally open contact is open if the alarm level has not
been reached (alarm relays) or the sensor is not in fault (fault relay). In energized mode, the normally open
contact is closed if the alarm level has not been reached (alarm relays) or the sensor is not in fault (fault
relay). Energized mode provides for fail-safe operation since a loss of power or cable failure will cause the
contact to be open.
4.1.2 Silenceable or Non-Silenceable
All alarms - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured to operate as silenceable, or non-
silenceable. If an alarm or fault is configured as non-silenceable, the corresponding alarm LED and relay,
once activated, will stay activated until the cause of the alarm or fault has cleared. If an alarm or fault is
configured as silenceable, the corresponding alarm LED and relay, once activated, can be deactivated by
acknowledging the Alarm Silence function on the front panel of the X40 controller or by activating the
external acknowledge switch if one has been installed (See section 7.1.4 ENTER and RESET/ACK
Switch).
4.1.3 Latching or Non-Latching Relays
All alarms - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured as either latching or non-latching.
In non-latching mode, the relay is deactivated as soon as the sensor alarm (alarm relays) or fault (fault
