TCS2-Logic Card

The Logic Card provides data processing of input-level detection signals from the Input card and provides output signals, received from TunnelWatch, to each relay of the Relay Card.

Connectors & indicators

The TCS2 Logic card has the following connections and indicators:

1.          Note: The Logic card connections are surfaced on the Motherboard, not the Logic card.

2.        Connectors.

a.        Interfaces to network port on Motherboard.

b.       Interfaces to fan connection on Motherboard.

3.        Indicators.

a.        TCP ACTIVITY LED: Yellow. Flashes to indicate network traffic.

b.       TCP LINK LED: Green. On steady to indicate a network connection.

c.        ADDRESS LED display: Displays the current address of the TCS2.

d.       CAN BUS ACTIVITY LED: Green. Flashes when activity is present on the CAN bus.

e.        CAN BUS ERROR LED: Red. On steady while there is a fault on the CAN bus.

4.       Controls.

a.        ADDRESS dial switch: 10 position rotary switch (0 through 9).

b.       RESET switch: Used to reset the Logic card.

Replacing

1.          Turn the TCS2 main power switch off.

2.        Note the ADDRESS dial switch setting of the Logic card that you are removing. On the new Logic card, set the ADDRESS dial switch to the same setting.

3.        Pull the Logic card out of its socket on the Motherboard.

4.       Align the new Logic card with the card guides in the Logic card slot on the motherboard.

5.        Push the Logic card firmly into the socket.

6.        Turn the TCS2 main power switch on.

Troubleshooting

1.          When the Logic card is successfully communicating with TunnelWatch, the LED display of the Logic card will show the Logic card address. On a system with only one TCS2, the address will generally be 1.

2.        If TunnelWatch cannot communicate with the TCS2 Logic card:

a.        The Logic card display will show a blinking "W" for Watchdog or a blinking "O" for Offline.

b.       If you have more than one TCS, verify that each ADDRESS setting is unique.

i.           Generally the primary TCS is set to 1.

ii.         The addresses must be unique even if one of your units is a TCS2 and the other is a legacy TCS (TCS1).

iii.       You SHOULD NOT change the address unless you find that two or more TCS units are sharing the same address. If you do change the address, you must press the reset button on the Logic card afterward.

c.        Verify the Ethernet cable connecting the TCS2 Motherboard to the TCS2 Network switch is securely connected (see image 3).

d.       Verify the Ethernet cables from the PC to the Ethernet switch are securely connected.

e.        Verify the TCS2 Ethernet switch power LED is on, and the Link/Activity lights for each port with a TCS2 Ethernet patch cable are blinking on the TCS2 Ethernet switch.

3.        If the red CAN BUS ERROR LED is on:

a.        Likely one or more of the Input, Conveyor or Relay cards is causing a CAN bus error.

b.       Pull out each plug-in card until the red CAN BUS ERROR LED goes out.

i.           Pull the Input card out of the TCS2.

●          If the CAN BUS ERROR LED turns off, the Input card is the problem and needs to be replaced.

●          If the CAN BUS ERROR LED does not turn off, push the Iinput card back in and continue troubleshooting.

ii.         If the CAN BUS ERROR LED is still on, pull out the Conveyor card. If the CAN BUS ERROR LED turns off, then the Conveyor card is the problem. If the CAN BUS ERROR LED is still on, repeat steps i. and ii. with the relay cards until the faulty card is found.

4.       If the Logic card display is blank, and no Logic card LEDs are on:

a.        Check the 5VDC LED on the TCS2 power supply assembly.

b.       If the 5VDC LED on the TCS2 power supply assembly is off, the TCS2 power supply assembly is the problem.

c.        If the 5VDC LED on the TCS2 power supply is on, but the Logic card’s display and LEDs are blank, the Logic card is the problem, and needs to be replaced.
