018 - Short Circuit

Figure 159: Warning 018-Short Circuit

A short circuit problem was detected on a station or device. The

warning screen displays the stations and devices that were on at

the time of short circuit detection. This alarm will occur whether

or not station limits have been enabled or disabled. Upon

detection, the controller immediately turns the station(s) off and

advances to the next station in the program. This insures that no

physical damage occurs to the controller by drawing too much

current.

Action:

Step 1 Too much current for a station is caused by improper

field wiring or valve solenoid failure.

a. Examine the station field wiring and look for an

inadvertent connection from the station field

wire directly to the controller common

b. Look for a direct connection from the station

field wire to earth ground

c. Look for a shorted solenoid in the valve

d. For warnings displaying multiple stations,

identify the defective station/device using the

Multi-Station Diagnostics procedure

Step 2 IMPORTANT:

Upon resolution of problem, CLEAR all warnings at

the satellites.
