Page 40: Open Collector Outputs (Open Collectr)
PD6908 Explosion-Proof & Intrinsically Safe Loop-Powered Process Meter Instruction Manual Open Collector Outputs (OPEN COLLECTR) The meter is equipped with two NPN open collector outputs as a standard feature that may be set up for pulse outputs, alarms, timed pulses, or disabled. - Page 41 PD6908 Explosion-Proof & Intrinsically Safe Loop-Powered Process Meter Instruction Manual Pulse Output (PULSE) The pulse outputs may be programmed to generate a scaled frequency based on the PV and a programmable factor. The factor determines the number of pulses per second 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 42 PD6908 Explosion-Proof & Intrinsically Safe 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. M AN, LATCH, L-CLEAR) determine how and when the alarm should be reset.
- Page 43 PD6908 Explosion-Proof & Intrinsically Safe Loop-Powered Process Meter Instruction Manual Flashing Red Alarm (RED) The last two lines in the preceding menu flow chart show how to program the display to turn red, flash, and display a message when an alarm occurs.
- Page 44 PD6908 Explosion-Proof & Intrinsically Safe Loop-Powered Process Meter Instruction Manual Stopwatch (STPWATCH) The stopwatch function may be used to manually run and control a process for a specific time interval up to 99 hrs., 59 min, and 59 seconds. The stopwatch function may be assigned to any open collector. There are three settings needed to use the function effectively.

Page 45: Solid-State Relay Outputs (Relay)
PD6908 Explosion-Proof & Intrinsically Safe Loop-Powered Process Meter Instruction Manual Solid-State Relay Outputs (RELAY) The meter can be optionally equipped with two solid-state relays that may be set up for alarms, timer, stopwatch, or pump control. Alternatively, they may be disabled. - Page 46 PD6908 Explosion-Proof & Intrinsically Safe 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. M AN, LATCH, L-CLEAR) determine how and when the alarm should be reset.
- Page 47 PD6908 Explosion-Proof & Intrinsically Safe 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).
- Page 48 PD6908 Explosion-Proof & Intrinsically Safe 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.
- Page 49 PD6908 Explosion-Proof & Intrinsically Safe Loop-Powered Process Meter Instruction Manual Pump Control with Alternation & Alarm Example The following is a typical application where the relays and open collectors are used for pump alternation and high and low level alarm.
- Page 50 PD6908 Explosion-Proof & Intrinsically Safe 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.

PD6908 Explosion-Proof & Intrinsically Safe Loop-Powered Process Meter Instruction Manual Advanced Process Variable Setup (ADV PV SETUP) The Advanced PV Setup menu contains options to apply input signal conditioning functions to the input and to scale/calibrate the input signal. Input Signal Conditioning Functions (FUNCTN) The Function menu is used to select the input signal conditioner applied to the input: linear, square root, programmable exponent, or round horizontal tank volume calculation. - Page 54 The square root function can be used to linearize the signal from a differential pressure transmitter and display flow rate in engineering units. PD6908 Displaying Flow Rate by Applying the Square Root Function to the Output of a DP Transmitter.
- Page 55 The PD6908, in combination with an ultrasonic level transmitter, makes for an economical way to measure and display open channel flow rate in most weirs and flumes. A guide such as the ISCO Open Channel Flow Measurement Handbook can provide the user with all the information needed: the exponent used in the flow equation for the desired flow units and the flow rate for any given head height.
