TS4-F/TS4-A-F/TS4-A-2F:
• Output voltage without active transmitter signal is 0.6V
• Output voltage with active transmitter signal will be normal
module V
MP
or V
OC
• If output is 0V contact Tigo support
Check that the system conforms to the design rules for TS4-F:
• Up to 10 strings per RSS Core (CT)
• Up to 30 modules per string
• String length up to 1000ft (total cable length from + to - )
• For longer distances please contact Tigo
• Homeruns through RSS Core must be the same polarity
(all positive or all negative)
• Match RSS Core polarity markings to ensure PLC signal ow in
the correct direction
RSS Transmitter:
• Power LED should be lit and Signal LED should be blinking during
operation
• Verify that RSS Core wiring and polarity are correct
• Power cycle RSS Transmitter if Signal LED is unlit
• While RSS Transmitter is powered off, string voltage should be
• TS4-F/TS4-A-F: 0.6V * number of modules
• TS4-A-2F: 0.6V * number of TS4s
• While RSS Transmitter is powered on, full string voltage should be
present
Test individual strings with active RSS Transmitter
one at a time in case of unexpected voltage.
