3. Check that the battery is properly seated in the battery holder.
4. Replace the battery.
BATT LOW LED remains on after the battery has been replaced.
Verify that the correct type of battery is being used. The LOW BATT LED remains
ON if an alkaline battery is used in TC Compact models with extended temperature
range operation.
CAUTION
Only use a 3.6 Volt lithium battery in TC Compact models with extended temperature
range operation.
Only use a 1.5 Volt alkaline battery in standard
TC Compact models.
• The 3.6 Volt lithium battery is designed to operate at both high and low temperature
extremes, and it provides a long service life in an extended temperature environment.
• The 1.5 Volt alkaline battery is not guaranteed to provide backup protection in
models with extended temperature range operation, even if the controller is operating
in a room-temperature environment.
• If a 3.6 Volt lithium battery is used in standard TC Compact
models, the battery
quickly discharges and provides much less backup protection than a 1.5 Volt alkaline
battery.
RUN LED
The RUN LED is on solid.
The RUN LED is steadily lit during normal operation to indicate that 24 Vac power
is ON and the application firmware has booted.
The RUN LED is ON. No communication is possible with the HMI port.
1. Verify that HMI port and your terminal are set to the same communication speed.
– The factory-default communication speed of the TC-16 and TC-24 HMI port is
9600 bps.
– The factory-default communication speed of the TC-36 HMI port is 115.2 Kbps.
2. Verify that the cable from the field panel to the operator's terminal is properly
connected at both ends.
3. Open the enclosure and verify that both ends of the HMI extension cable are
properly connected.
4. Unplug the extension cable and plug directly into HMI port.
The RUN LED is off.
1. Verify that power is connected.
2. Check the service box and transformer ON switches.
3. If power is ON, verify that the application firmware has booted.
4. Measure voltage on 24V~ and (Terminals 1 and 2).
