MICRONOR automation components 3.4. System Start-Up & Performance Check Connect +24VDC supply and ground to the designated terminals on the controller module. Verify that the ‘POWER’ LED (green) is illuminated. If the emergency switch is not connected, do so at this time and also verify that the ‘EMERGENCY ON’ LED (red) turns off as the switch is connected. -
Page 12: Troubleshooting
• Verify controller module power supply is +24VDC with a current output of at least 80mA. • Contact Micronor Sales for further assistance. 4.1.2. ‘Emergency ON’ illuminated w/Emergency Switch Connected • Check if emergency switch is ‘On’ when depressed. If so, reset switch and verify ‘Emergency ON’... -
Page 13: Relay Switching Failure
• Verify when switch is depressed, the controller will electro-mechanically switch the state of the relay resulting in a faint ‘click’ sound. • Contact Micronor Sales for further assistance. 4.1.6. Damaged Emergency Switch (Fiber) • Verify controller module outputs optical power by connecting LC loopback directly from one LC connector to the other, shown in Figure 10. -

Page 20: Theory Of Operation
MICRONOR automation components 7. Theory of Operation A functional block diagram is shown in Figure 11, showing the Switch Sensor, Optical Link and Controller Module. The switch is connected by a duplex fiber optic cable of readily available 50/125µm or 62.5/125µm multi-mode fiber. The transmit fiber guides steady optical power from a near-IR light source to the optical switch. -
Page 21: Application Notes
MICRONOR automation components 8. Application Notes 8.1. Determining System Loss Budget For Chaining Multiple Switches The MR380-1 controllers have the capacity to chain multiple switches in series permitting that the additional losses fall within the system optical loss budget. Figure 12 illustrates a system using three MR380-2 switches in series. - Page 22 MICRONOR automation components System Component Loss(dB) Quantity Calculation(db) Loss(dB) Length of Fiber 3 dB/km 0.5 km x 2 The sum of Connections all losses Switches Total Loss The total system loss is 11dB, which is under the maximum 15dB system loss margin. Thus, the system should have no issues functioning under this configuration.
