009 - Off Line

Figure 150: Warning 009-Off line

A satellite has lost hardwire communications with its submaster.

Hardwire communications occur between the submaster and its

satellites at the rate of once every 0.1 seconds. Loss of

communications may be temporary (power glitch) or permanent

(severed EV-CAB-COM communications cable). In either case,

irrigation will continue at the satellites without interruption as

long as the configuration does not utilize the Flow Max feature.

This message will be accompanied by a corresponding message

at its submaster, "HW COMM FAILURE."

Action:

Step 1 Hardwire communications failures may be caused by

any of the following: power failures, improper

hardwire connections at the communications board,

or broken/severed communications cable.

Step 2 Starting with the first satellite which is connected to

the submaster, examine the satellite address to verify

address XX-01 appears in the LCD display. If there

is no address and the controller is on, then a problem

related to the communications cable or its

connections has occurred somewhere between the

submaster and this unit. If the address is OK,

examine the satellite warning list for any related

warning messages, e.g. momentary power failure. If

address is OK and there are no related warnings,

proceed to the next satellite and troubleshoot as

above. Because the communications cable is wired
