Multi-Function System Display - SymCom 601 Installation Instructions Manual

HF- "HF" setting is the High Frequency Trip threshold. Using the NEMA MG1 standard on a 60Hz
system, "HF" = 60 x 1.05 = 63Hz.
TD1- "TD1" is the Trip Delay time for voltage and frequency faults. This includes voltage unbalance,
low voltage, high voltage, low frequency and high frequency. A setting of 5-10 seconds is
normally a good place to start for these types of faults.
TD2- "TD2" is the Trip Delay time for single-phasing faults. A setting of 2-4 seconds is a good place to start.
RD1- "RD1" is the rapid cycle timer. It will engage when the MotorSaver is first powered-up. An "RD1"
setting of 20-30 seconds will generally protect the motor from rapid, successive power outages.
A setting of 0 seconds will allow the motor to start immediately after power-up.
RD2- "RD2" is the restart delay after a fault occurs. This delay allows the motor to cool down after
experiencing a fault. It is also known as a motor cool down timer. Your motor manufacturer
should be contacted to determine this setting. Under normal circumstances, a setting of 300
seconds will give the motor enough time to cool down between faults.
#RF- "#RF" is the type of reset after a fault. A setting of "0" is manual reset and a setting of "A" is
continuously automatic.
ADDR- "ADDR" is the address setting for RS485 communications. Available settings are from A01 - A99.
You may ignore this setting if RS485 communications are not used.
1LFT, 2LFT, 3LFT, 4LFT- These positions are the last four faults stored in memory. Note: The motor
will be shut down when accessing these positions. Also, the last fault may be displayed by
pushing the "RESET" button at any time during normal operation.

MULTI-FUNCTION SYSTEM DISPLAY

The output display can show various system operating parameters:
• L1-L2 Voltage
• % Voltage Unbalance
When the "MODE SELECT" switch is in the "RUN" position, the LED will display one of the above
operating parameters. To select or change the displayed parameter, turn the "DISPLAY / PROGRAM"
adjustment to the desired position as shown on its label.
The multifunction display also announces system faults such as low voltage, high voltage, single
phasing, voltage unbalance, and reverse phasing errors. Any time the "MODE SELECT" switch is in
the "RUN" position, the "RESET/PROGRAM" button may be pushed to view the last fault which
occurred. The table on page 4 shows the possible messages. To view the previous faults, rotate the
"MODE SELECT" switch to the corresponding last fault. NOTE: Rotating the "MODE SELECT"
switch out of the run position will de-energize the Model 601's contacts and shut down the motor.
