Prerequisite for power up
Ensure power and ground wiring to the controller is ready. See “Earth ground and power”. See Figure 10 for the location of status LEDs.
Steps
1. Apply power. To do this, do one of the following:
• Insert the 2-position 24V power connector plug, or
• Insert the barrel plug of the wall-mount AC adapter (Model Number: ZHWPWADTR).
2. Check the STAT (Status) and BEAT (Heartbeat) LEDs.
When power is applied, after 3-10 sec, the green “STAT” LED illuminates, indicating that the system is OK, with power applied. During
bootup, the “BEAT” LED may blink at 1 Hz with a 90%/10% on/off duty cycle, or in some other irregular pattern. When bootup completes, the
normal 1 Hz “BEAT” LED flash at 50%/50% on/off duty cycle returns.
If after applying power, the “STAT” LED goes out, or if the “BEAT” LED comes on (steady) and stays lit over 2 minutes, contact Technical
Support for assistance.
