INM 5500 Rev 1039Switch input operationIf switch contacts are used for this Pulse Input (terminals 1 & 2), then and parallel resistorsmust be fitted - see Section 6.1.2 for recommended values.Simple or Legacy mode - SW4 - OFFIf simple “pulse-in/pulse-out” operation is required or, if a replacement for the earlier MTL5032pulse isolator is required, then SW4 should be set to OFF. The input switching point voltage(Vsp) thresholds can then be defined by Switches 1 & 2, and the LFD operation can be set withSwitch 3. When Switch 3 is ON, the Alarm output (terminals 11 & 12) become active.Configurable mode - SW4 - ONIn this mode, analogue, alarm and pulse outputs are available but the module must be softwareconfigured to define its operating mode. In this mode, software controls the LFD function andSwitch 3 has no effect. Switches 1 & 2 continue to define the switching point threshold (Vsp).Configuration requires a personal computer, a PCL45USB interface and PCS45 software. SeeSection 6.9 for details of the configurator.Alarm inhibitingThe Inhibit input is provided to inhibit alarm output operation. This facility is useful, for example,during power-up, when pulse rates are below the alarm threshold. When normal operationalvalues are established the inhibit can be disabled. Such a facility is sometimes referred toas a start-up delay. Inhibit is enabled by connecting a switch or proximity detector betweenterminals 6 and 3. If switch contacts are used for this input, then and parallel resistors must befitted - see Section 6.1.2 for recommended values.LED indicatorsUse the following LED information to understand the module status.LED DescriptionPWRPower (green) ON - Power OK OFF - No power or insufficient voltageO/POutput (yellow)The LED will follow the pulse output state. If the output is pulsing thenthe LED brightness will pulse. If the pulsing is rapid or very short, the LEDmay dim if it is unable to respond to such changes.If the output is high, the LED will be ON.STSStatus(red - flashing)In legacy mode a line fault will cause the LED to turn ON.In mC mode, the LED is programmable to display a line fault or an Alarmtrip operation. In the event, it will also indicate a mC fault condition.
