MGB Help for Setup and Service 1 Connection 1.1 Connection of the buttons in the MGB The terminal assignment of the switches (lights, buttons, emergency stop, etc.) in the cover of the MGB is not described in the system manual. These terminals can be found in the associated data sheet of the MGB included with every delivery. Please contact EUCHNER if the data sheet has been lost, and you will promptly be sent a data sheet. Alternatively, you can look in the MGB catalog.
MGB Help for Setup and Service 2 Teach-in operation 2.1 Preparing device for teach-in operation Connect the MGB as shown below, but do not apply any voltage to UB yet. Observe different control of guard locking for MGB-L1 and MGB-L2. Note: In case of AR configuration: For the teach-in standby state, FI1A and FI1B must be connected to DC 24 V. Every MGB taught-in individually before a switch chain is set up.
MGB Help for Setup and Service 2.2 Teaching in handle module 1. Insert bolt tongue into the evaluation module. 2. Switch on operating voltage UA and UB. In case of AR configuration: The green LED (State) flashes quickly (approx. 5 Hz). A self-test is performed during this time (approx. 8 s). If the red LED (DIA) is illuminated, there is a fault. Teach-in is not possible. The green LED (State) indicates the fault code. Refer to the “System status table” in the respective system manual for diagnostics.
MGB Help for Setup and Service 3 Troubleshooting 3.1 LED DIA illuminated + LED STATE not illuminated (AR and AP modes) Fault symptom: The MGB displays the fault state “internal fault”. Possible fault causes: Data error Locking arm blocked Internal component fault Remedy: 1. Check whether the locking arm is blocked (possibly by the bolt of the handle module). 2.
MGB Help for Setup and Service 3.3 LED DIA illuminated + LED STATE flashes 2 times (single wiring – only AR mode) Fault symptom: The MGB displays the fault state “input error (e.g. missing test pulses)”. Possible fault causes: 24 V DC missing at inputs Fl1A and/or Fl1B A safety evaluation device or a safe control system with clocking outputs is connected to FI1A and/or FI1B. Remedy: 1. Check the wiring and correct it if necessary or switch to AP mode. 2.
MGB Help for Setup and Service All connections are correct, but there is no common potential for the series-connected devices (several power supply units for one chain) In case of series operation, an upstream unit is set as an AP unit. Remedy: 1. Check the wiring and correct it or switch the clock pulses off or check the upstream devices for incorrect DIP switch configuration. 2.
MGB Help for Setup and Service 3.6 LED DIA illuminated + LED STATE flashes 4 time (AR and AP modes) Fault symptom: The MGB displays the fault state “output fault”. Possible fault causes: The connected control system and the MGB do not have a common reference potential (common ground) A ground loop has been produced by bridges having been installed both on the MGB and in the control cabinet (refer to the system manual for this purpose). The internal output circuit is damaged.
MGB Help for Setup and Service 3.8 LED DIA not illuminated + LED STATE not illuminated or does not flash Possible causes: Teach-in operation complete. DIP switch 5 still set to “ON” (AP/AR configuration process not fully completed yet). Remedy: When the teach-in operation is complete, the operating voltage must then be switched off at the locking module for at least 3 minutes in order to activate the taught-in code of the handle module in the locking module.
