Visual Status and Operational Feedback
What are all these blinking lights?
Your Z-MAX relay cabinet has a variety of feedback mechanisms which are designed
to alert you as to how your panel is operating and the current status of each relay.
The main feedback mechanism, the LCD display is covered at the beginning of the
“User Interface” chapter. The feedback mechanisms we’re discussing here cover all
of the red, amber, or green LED’s inside the panel.
The LED’s inside the panel can be broken up into two categories, ‘System Status’ and
‘Relay Status’ LED’s.
System Status LED’s
System Status LED’s are designed to tell you at a quick glance the operational
characteristics of your system. For example, whether or not your system is receiving
data on one of the communication lines! This will assist you and our technical support
team should any diagnostics be necessary.
Use the following table to determine the possible colors and patterns of the LED’s
which represent their status.
Generally, the following conventions apply:
• Green – All Systems Go! No alerts detected.
• Flashing Green – All Systems Go! Receiving or transmitting data.
• Solid Red – Alert Condition. Specific alert depends on LED
• Slow Flashing Red – Systems operating Normally, usually a heartbeat
• Quick Flashing Red – Alert Condition or Override Condition, specific alert depends
on LED.
The specific functions and states of each LED are listed below:
