Primary/Standby : Shows the condition of the CPU with regard to controlling the option
modules. The Primary CPU is in control. A Standby CPU is prepared to
become the Primary and take control if the partner unit fails.
Module Health : Indicates the absence (green light) or presence (red light) of a fault on the
CPU.
ESD Presence : Shows a yellow light if an Emergency Shut Down signal is active.
Redundancy : Shows a green light if there is a partner module fitted.
Option
Other Master : Indicates the absence (green light) or presence (red light) of a fault on the
Station health partner CPU.
Alarm : Indicates the presence of an alarm (red light) somewhere on the system.
Option 1 and Option 2 - Show the type of Option module fitted, either:
Pakscan 2 Loop Option Module
Loopback in : A blue light shows whilst the master station is reconfiguring the loop.
Progress
Loopback in Use : A yellow light shows when the master station has detected a loopback fault
on the system.
Auto Loopback : If a fault occurs on the network and an automatic reconfiguration of the
occurred loop occurs, then a yellow light is shown here.
Common Field : A red light shows if any field unit on the network has an alarm bit present.
Unit Alarm
Common : A red light shows if any actuator on the network is unavailable due to its
Actuator Alarm monitor relay having tripped.
ESD Active : If there is an Emergency Shut Down signal present on the system a red
light shows.
Pakscan 3 Wireless Option Module
Configuration in
Progress
: A blue light shows whilst the master station is reconfiguring the network.
Network Healthy
: A Green light shows when the master station has detected NO faults in
the network and it is healthy.
Field Unit Alarm
: A Red light shows when the master station has detected an alarm on
any of the field units.
Field unit Comms
fail
: A Red light shows when the master station has detected a
communications failure to a field unit.
ESD Active
: If there is any Emergency Shut Down signal present for that network on
the system a red light shows.
Controls - Not Available for Read level users
Network ESD : Click here to issue an ESD to all actuators connected to both option
modules. The resulting action will depend on the individual actuator
settings. A confirmation screen appears to verify or cancel the instruction
before the action occurs.
Changeover : Only applicable to hot standby systems. Click this button to make the
Master master station CPU in control; change from A to B or B to A.
