Relays
Relays 1, 2 & 3 share a common return. Only the NO contact is available, however each relay
can be configured to be NO or NC for the alarm condition.
Relays 4 & 5 each have their own return connection. Only the NO contact is available, however
each relay can be configured to be NO or NC for the alarm condition.
The specification for the relay contacts can be found on page 138.
MMI (Man Machine Interface)
The EFX48 contains a 128 x 32 high contrast monochrome OLED display. This is used to display
system measurements, alarms, configuration data and system set-up via a menu/page system –
see page 151 for a map of the menu / page structure.
The menu / page structure is navigated by using the navigation joystick to the right hand side
of the display. The navigation switch has UP, DOWN, LEFT, RIGHT and ENTER switches.
Switch operation is acknowledged by key beep if key sounds have been enabled in the
configuration file – see page 79 for details on how to enable/disable key beeps.
The display can be configured to automatically turn off after a period of inactivity. See
configuration parameters on page 116.
Ethernet
Static and DHCP Addressing
The EFX48 supports DHCP, allows a static IP address to be set, or it can serve an IP address to a
computer device when direct connected (that is when the computer is connecting directly using
a web browser as a GUI).
SNMP
The product supports SNMP standards V1, V2, and V3 with relevant security, authentication
and privacy settings.
A MIB file is contained within the EFX48 and this can be downloaded from the unit via the Web
pages.
• Up to 8 trap receivers can be configured.
• Trap repeat can be enabled with a configurable repeat rate.
• System Object ID is configurable. EFX48 uses the common Eaton System Object ID of
534, and the DC Power System controller Branch under that of {Eaton 11}.
• All alarms that are set to warning, minor or major are forwarded to all active SNMP
trap receivers.
