  • Page 25: Open Collector Outputs (Open Collectr)

    DataLoop™ LI23 Loop-Powered Process Meter Instruction Manual Open Collector Outputs (OPEN COLLECTR) The meter is equipped with two NPN open collector outputs that may be set up for pulse outputs, alarms, timed pulses, or disabled. Pulse outputs can be set to transmit the PV value (PV1 or PV2 if meter is in dual-scale mode). Output 2 may be used to generate a quadrature output based on the other open collector output.
  • Page 26 DataLoop™ LI23 Loop-Powered Process Meter Instruction Manual Pulse (PULSE) Pulse outputs may be assigned to output the PV at a programmable factor. The factor determines the number of pulses per second which should be generated per unit of measure. For example, if the meter display shows 100 gallons and the factor is set to 2, the number of pulses generated per second would be 200.
  • Page 27 DataLoop™ LI23 Loop-Powered Process Meter Instruction Manual Alarm (ALARM) Alarm outputs may be assigned to the PV or the digital input. When assigned to the PV, the alarm may be set as either a high alarm or a low alarm. Alarm actions ( AUTO , AUTO.MAN , LATCH , L‐CLEAR ) determine how and when the alarm should be reset.
  • Page 28 DataLoop™ LI23 Loop-Powered Process Meter Instruction Manual Timer (TIMER) The timer output may be set to generate the timed pulse only once ( ONESHOT ) or continuously ( CONT ). The timer output produces a constant width pulse at a constant frequency, if set as continuous timer. Program the Off Delay ( OFF.DLAY ) from 1 second to 99 hours 59 minutes and 59 seconds.

  • Page 29: Solid State Relay Outputs (Relay)

    DataLoop™ LI23 Loop-Powered Process Meter Instruction Manual Solid State Relay Outputs (RELAY) The meter is optionally equipped with two solid state relays that may be set up for alarms, timer, or pump control. Alternatively, they may be disabled. Alarms are available based on the PV value or the digital input. The alarm status will show on the display even if the output is not wired.
  • Page 30 DataLoop™ LI23 Loop-Powered Process Meter Instruction Manual Alarm (ALARM) Alarm outputs may be assigned to the PV or the digital input. When assigned to the PV, the alarm may be set as either a high alarm or a low alarm. Alarm actions ( AUTO , AUTO.MAN , LATCH , L‐CLEAR ) determine how and when the alarm should be reset.
  • Page 31 DataLoop™ LI23 Loop-Powered Process Meter Instruction Manual Pump Control (PUMPCTRL) The pump control output is used in situations where the relays are used to control pumps. There are two options available for controlling pumps: on-off ( ON‐OFF ) and pump alternation ( ALTERN ). ON‐OFF will turn the relay on at a programmed on point and off at a programmed off point.
  • Page 32 DataLoop™ LI23 Loop-Powered Process Meter Instruction Manual Pump Alternation (ALTERN) Pump alternation sets the two relays to alternate every time the first on point ( ON 1 ) is reached. The active relay will turn off once the first off point ( OFF 1 ) is reached. If the PV reaches the second on point ( ON 2 ), the other relay will also turn on.
