situation, the limit checked by the controller is the sum of the

individual station current limits.

Maximum Controller Current

The maximum rated current for any station or combination of

stations is 2.0 Amps. If four devices (field valve solenoid,

Master Valve, Pump, Relay, etc.) that each have current draw of

.50 Amps were on simultaneously, the current would be 2.0

Amps. This is equal to the maximum controller allowance.

Monitor individual station currents and program your stations

accordingly. If you are using older solenoids which draw more

than .50 Amps each, you may consider replacing them.

The controller protects itself in the event that the solenoids draw

more than the maximum allowable current. The associated

station will shut down and the following message will be

displayed:

Figure 194: Short Circuit Warning

For further details on short circuit warning, refer to Chapter 10.

In addition to the built-in short circuit protection, a separate 24

VAC fuse exists (located on the Master Valve/Pump/Power

Assembly board).

In the rare event that the 24 VAC fuse should blow, the

controller has intelligence to detect the blown fuse and inform

the operator with the following message:
