Select Analog Output: This switch selection allows each analog output to be multiplexed into two outputs. If the switch is active, the parameter assigned in setpoint S2 SYSTEM SETUP ÖØ ANALOG OUTPUT 1 ÖØ ANALOG OUTPUT 1 ALT determines the output level. If the switch is not active, the parameter assigned in setpoint S2 SYSTEM SETUP ÖØ ANALOG OUTPUT 1 ÖØ ANALOG OUTPUT 1 MAIN is used. See the following section and 5.3.2: Analog Outputs for additional details. • Select Analog Input: This switch selection allows the analog input to be multiplexed into two inputs. If the switch is active, the parameter assigned in setpoint S2 SYSTEM SETUP ÖØ ANALOG INPUT ÖØ ANALOG INPUT ALT is used to scale the input. If the switch is not active, the parameter assigned in setpoint S2 SYSTEM SETUP ÖØ ANALOG INPUT ÖØ ANALOG INPUT MAIN is used. If a relay is assigned in S2 SYSTEM SETUP ÖØ ANALOG INPUT ÖØ ANALOG IN MAIN/ALT SELECT RELAY, that relay energizes when the switch is active and de-energizes when the switch is not active, thus providing the ability to feed in analog inputs from two separate sources as shown in the figure below. See the 2.2.10: Analog Input (Optional) section below for details. Refer to 5.3.3: Analog Input for additional details

Analog Outputs (Optional)

The PQMII has four current outputs when the transducer option is installed (T20 = 4 to 20 mA, T1 = 0 to 1 mA in the order code). These outputs can be multiplexed to produce 8 analog transducers. This output is a current source suitable for connection to a remote meter, chart recorder, programmable controller, or computer load. Use the 4 to 20 mA option with a programmable controller that has a 2 to 40 mA current input. If only a voltage input is available, use a scaling resistor at the PLC terminals to scale the current to the equivalent voltage. For example, install a 500 Ω resistor across the terminals of a 0 to 10 V input to make the 4 to 20 mA output correspond to 2 to 10 V (R = V/I = 10 V / 0.02 A = 500 Ω). Current levels are not affected by the total lead and load resistance which must not exceed 600 Ω for the 4 to 20 mA range and 2400 Ω for the 0 to 1 mA range. For readings greater than full scale the output will saturate at 22 mA (4 to 20 mA) or 1.1 mA (0 to 1 mA). These analog outputs are isolated and since all output terminals are floating, the connection of the analog output to a process input will not introduce a ground loop. Part of the system should be grounded for safety, typically at the programmable controller. For floating loads (such as a meter), ground Terminal 24 externally.

• Aux 1/2/3 Relay: When a switch input is assigned to an Auxiliary relay, a closure on the switch input causes the programmed auxiliary relay to change state. This selection is available only if the Control (C) option is installed. • Clear Energy: When a switch input is assigned to “Clear Energy”, a closure on the switch input will clear all Energy data within the PQMII. • Clear Demand: When a switch input is assigned to “Clear Demand”, a closure on the switch input will clear all Demand data within the PQMII.
