  • Page 9: General Information

    1 • CEM-2020 General Information The optional CEM-2020 is a remote auxiliary device that provides additional DGC-2020ES contact inputs and outputs. Two types of modules are available. A low current module (CEM-2020) provides 24 contact outputs and high current module (CEM-2020H) provides 18 contact outputs.
  • Page 10 Tested in close proximity to an unshielded, unsuppressed Altronic DISN 800 ignition system. HALT (Highly Accelerated Lift Testing) HALT is used by Basler Electric to prove that our products will provide the user with many years of reliable service. HALT subjects the device to extremes in temperature, shock, and vibration to simulate years of operation, but in a much shorter period span.

  • Page 11: Functional Description

    The CEM-2020 provides 24 programmable contact outputs with the same functionality as the contact outputs on the DGC-2020ES. Outputs 5 through 16 can carry 1 A. Outputs 17 through 28 can carry 4 A. The label text of each contact output is customizable.

  • Page 15 Contact Inputs and Contact Outputs The CEM-2020 (Figure 1-3) has 10 contact inputs and 24 contact outputs. The CEM-2020H (Figure 1-4) has 10 contact inputs and 18 contact outputs. Figure 1-3. CEM-2020 Contact Input and Contact Output Terminals DGC-2020ES CEM-2020...
  • Page 16 These terminals provide communication using the SAE J1939 protocol and provide high-speed communication between the Contact Expansion Module and the DGC-2020ES. Connections between the CEM-2020 and DGC-2020ES should be made with twisted-pair, shielded cable. CAN interface terminals are listed in Table 1-2. Refer to Figure 1-5 and Figure 1-6.

  • Page 21: Troubleshooting

    9469200997 2 • Troubleshooting If you do not get the results that you expect from the DGC-2020ES, first check the programmable settings for the appropriate function. Use the following troubleshooting procedures when difficulties are encountered in the operation of your genset control system.
  • Page 22 Use a voltmeter connected between the BATT– terminal (17) and the SENDER COM terminal (2) on the DGC-2020ES to verify that there is no voltage difference at any time. Any voltage differences may manifest themselves as erratic sender readings. Wiring should be corrected so that no differences exist.

  • Page 23: Ground Faults Detected In Ungrounded System Applications

    Step 3: If ground faults are detected on a DGC-2020ES in an ungrounded system application, it is recommended that potential transformers be employed on the voltage sensing inputs to provide full isolation between the DGC-2020ES and monitored voltage phases.
  • Page 24 9469200997 Step 8: Verify the wiring to the breaker from the DGC-2020ES. If it seems OK, you can do a manual close and open by modifying the programmable logic. Map some unused outputs to the OPEN and CLOSE outputs from the Gen Breaker Block in the programmable logic. Map a virtual switch to the logic output that would normally be the breaker open output.
