B.2 Dual Solar Cell (Only Available on 50-0-50 Volt Controller)

The solar cell facility can be modified to enable two solar cell outputs to be monitored.

The solar cell outputs are connected via two relays to two controller inputs. One of the

solar cells will then cause the controller to change between dim and bright in the

normal manner. The part number for the dual solar cell kit is 667/1/21020/000.

The two solar cell outputs are monitored and when either of the following two fault

conditions occur the signals will be set to the non-dimmed state.

1. If both solar cells outputs remain in the same state for more than 16 hours. This

is adjustable in the range of 0 to 255 hours using handset command PIR0. The

value which is assigned to handset command PIR0 will give required monitor

time in hours, with the default setting being 16.

2. If the solar cell outputs are in different states for more than 45 minutes. This is

adjustable in the range of 0 to 255 minutes using handset command PIR1. The

value which is assigned to handset command PIR1 will give required monitor

time in minutes, with the default setting being 45.

When either of the above two faults occur the controller fault log 27 will be set as

shown below. The fault log will remain set until reset using the handset. While the fault

log is active the signals will be held in the non-dimmed state.

FLF 27 = 1 If the solar cell outputs remain in the same state for more than 16 hours.

FLF 27 = 2 If the solar cell outputs are in different states for more than 45 minutes.

FLF 27 = 3 If both the above two conditions occur.

Additional hardware and configuration information is required to enable this facility.
