F
4.3.1.1.
Phase Loss fault indicates that the unit has lost feedback from L3 on the AC
connections. This fault clears itself 10 seconds after the condition is cleared.
4.3.1.2.
Over Temp fault indicates that some internal components have exceeded
their operating temperatures. This fault will clear after the unit cools down.
4.3.1.3.
Over Voltage fault occurs when the internal DC bus voltage rises to unsafe
levels during operation. This fault clears itself 10 seconds after the condition
is cleared.
4.3.1.4.
This fault indicates the internal transistor drive circuitry has detected an error.
This fault must be manually cleared as it usually indicates a failure elsewhere
in the system.
S
4.3.2.
Additionally, there are several system faults that indicate the
microprocessor has encountered a critical error. These faults are indicated
by a SOLID RED LED and a FLASHING YELLOW LED.

All of the user inputs to the M3545P are 24VDC, active-high logic, and must be
referenced to TB-7. The outputs are dry contacts that close to the output common:
TB-9.
N/C (TB-6)
4.4.1.
This is a spare input reserved for future use and has no function at this time.
I
4.4.2.
NPUT
All user inputs are referenced to this terminal.
F
4.4.3.
Activating this input while the unit is idle will cause it to blink out the most
recent fault state.
