010 - Hardwire Communication Failure

Figure 151: Warning 010-Hardwire Communication Failure

A submaster has lost hardwire communications comm. with one

or more satellites. 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 one or more satellites, "OFFLINE."

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
