Rain Master RME HAWK, Руководство пользователя

Страница: 46 / 72

= The problem is a station upper flow limit violation. The
station lights illuminate to show which station(s) are
involved. Pressing the REVIEW key again reveals the
measured GPM at the time the fault occurred.
Whenever a specific fault is displayed it can be cleared by pressing the CLEAR key.
Alternatively, if CLEAR is not hit, the QUIT key will return the controller back into the
AUTOMATIC mode without clearing the fault condition.
Refer to the fault type(s) defined below for specific information.
WIRING FAULT
The RME HAWK has been equipped to detect station short circuits which may occur
due to improper field wiring or faulty valve solenoids. In the event a station draws excessive
electrical current, the following action occurs:
• The offending station will be immediately turned off.
• The next scheduled station of the program will be started.
• FAULT…PRESS…REVIEW…appears in the display
• The controller will continue to execute programs, however, any faulted station(s)
will not be turned on again.
Note: If multiple stations are on simultaneously, and the controller detects an overcurrent
fault, all running stations will be diagnosed as faulty.
Note: If a short circuit occurs at the normally closed master valve and the program
has been SETUP to use a master valve, the controller will successively condemn all
remaining stations in the program. Upon reviewing the fault, all stations of the
program shall illuminate, indicating that the problem appears at the master valve.
User Action:
1. Excessive station current may be due to an inadvertent direct connection between the
station wire and the common wire
2. Check for exposed wiring in a flooded valve box
3. Check for a faulty valve solenoid.
4. When corrective action has completed, the fault should be cleared.
FLOW MAIN FAULT
The main line flow limit for the controller has been exceeded.
• All present irrigation (running programs) are terminated.
• FAULT…PRESS…REVIEW…appears in the display
• If the master valve for the controller has been SETUP as a normally open (NO)
master valve, then this terminal will be energized with 24 VAC (master valve
is closed).
