DataView™ LI55 Level Controller Instruction Manual

INTRODUCTION

The DataView LI55 is a multi-purpose, easy to use digital process meter ideal for level, flow rate, temperature, or pressure transmitter applications. It accepts current and voltage signals (e.g. 4-20 mA, 0-10 V). Three of the front panel buttons can be custom-programmed for a specific operation. The analog input can be scaled to display the process in two different scales; for example the main display could indicate level in feet and the second display could indicate the volume in gallons.

The basic model includes an isolated 24 VDC transmitter power supply that can be used to power the input transmitter or other devices. An additional isolated 24 VDC power supply is included with the 4-20 mA output option. A digital input is standard.

A fully loaded LI55 meter has the following: four SPDT relays, 4-20 mA output, and two 24 VDC power supplies. The LI55 capabilities may be enhanced by adding a four SPST relays expansion module (creating an eight-relay process meter).

The eight relays can be used for alarm indication or process control applications, such as pump alternation control. The 4-20 mA isolated output, and digital I/O options make the LI55 an excellent addition to any system.

Switching Inductive Loads

The use of suppressors (snubbers) is strongly recommended when switching inductive loads to prevent disrupting the microprocessor’s operation. The suppressors also prolong the life of the relay contacts. Suppression can be obtained with resistor-capacitor (RC) networks assembled by the user or purchased as complete assemblies. Refer to the following circuits for RC network assembly and installation:

Figure 13. AC and DC Loads Protection

Choose R and C as follows: R: 0.5 to 1 Ω for each volt across the contacts C: 0.5 to 1 µF for each amp through closed contacts

Notes:

1. Use capacitors rated for 250 VAC.

2. RC networks may affect load release time of solenoid loads. Check to confirm proper operation.

3. Install the RC network at the meter's relay screw terminals. An RC network may also be installed across the load. Experiment for best results.

Use a diode with a reverse breakdown voltage two to three times the circuit voltage and forward current at least as large as the load current.

Interlock Relay Feature

As the name implies, the interlock relay feature reassigns one, or more, alarm/control relays for use as interlock relay(s). An Interlock contact is wired to the digital input and triggers the interlock relay. This feature is enabled by configuring the relay and digital input (see page 70).

In one example, a dry interlock contacts are connected in series to the F4 digital input which will be used to force on (energize) the assigned interlock power relay when all interlock contacts are closed (safe). The interlock relay front panel LED flashes when locked out. The interlock relay would be wired in-series with the load (N/O contact). See below.

Programming the Meter (proG)

It is very important to read the following information, before proceeding to program the meter:

 The meter is factory calibrated prior to shipment to read in milliamps and

volts depending on the input selection. The calibration equipment is certified to NIST standards.

 Use the Scale menu to scale the process input (e.g. 4-20 mA). A calibrated

signal source is not needed to scale the meter.

 Use the Calibrate menu to apply a signal from a calibrator or a flowmeter.

 The LI55 is a single input meter with dual-scale capability.

The Program menu contains the Scale and the Calibrate menus.

Note: The Scale and Calibrate functions are exclusive of each other. The meter uses the last function programmed. Only one of these methods can be employed at a time. The Scale and Calibrate functions can use up to 32 points (default is

2). The number of points should be set in the Advanced menu under the Multi-

Point Linearization (Linear) menu selection prior to scaling and calibration of the meter, see page 81 for details.

If the dual-scale level feature is selected in the Setup menu, the Scale 1 and Scale 2 menus are enabled for PV1 & PV2 respectively.

The process input may be calibrated or scaled to any display value within the range of the meter.

The On time delay is associated with the set point. The Off time delay is associated with the reset point.

Relay Action for Loss of 4-20 mA Input (Loop Break)

The loop break feature is associated with the 4-20 mA input. Each relay may be programmed to go to one of the following conditions when the meter detects the loss of the input signal (i.e. < 0.005 mA):

1. Turn On (Go to alarm condition)

2. Turn Off (Go to non-alarm condition)

3. Ignore (Processed as a low signal condition)

Note: This is not a true loop break condition; if the signal drops below 0.005 mA, it is interpreted as a “loop break” condition.

RELAY OPERATION DETAILS

Overview

The relay capabilities of the meter expand its usefulness beyond simple indication to provide users with alarm and control functions. These capabilities include front panel alarm status LEDs as well as either 2 or 4 optional internal relays and/or 4 external relays expansion module. Typical applications include high or low temperature, level, pressure or flow alarms, control applications such as simple on/off pump control, and pump alternation control for up to 8 pumps. There are four basic ways the relays can be used:

1. High or Low Alarms with Latching or Non-Latching Relays

2. Simple On/Off Control with 100% Adjustable Deadband

3. Sampling (Based on Time)

4. Pump Alternation Control for up to 8 Pumps

Relays Auto Initialization

When power is applied to the meter, the front panel LEDs and alarm relays will reflect the state of the input to the meter. The following table indicates how the alarm LEDs and relays will react on power-up based on the set and reset points:

Alarm # HI or LO

Alarm

1 HI 1000 500 499 Off

Front Panel LEDs

The LEDs on the front panel provide status indication for the following:

LED Status LED Status

1 Alarm 1 5 Alarm 5

2 Alarm 2 6 Alarm 6

3 Alarm 3 7 Alarm 7

4 Alarm 4 8 Alarm 8

The meter is supplied with four alarm points that include front panel LEDs to indicate alarm conditions. This standard feature is particularly useful for alarm applications that require visual-only indication. The LEDs are controlled by the set and reset points programmed by the user. When the display reaches a set point for a high or low alarm, the corresponding alarm LED will turn on. When the display returns to the reset point the LED will go off. The front panel LEDs respond differently for latching and non-latching relays.

For non-latching relays, the LED is always off during normal condition and always on during alarm condition, regardless of the state of the relay (e.g. Relay acknowledged after alarm condition).

For latching relays, the alarm LEDs reflect the status of the relays, regardless of the alarm condition. The following tables illustrate how the alarm LEDs function in relation to the relays and the acknowledge button (Default: ENTER key):

Latching and Non-Latching Relay Operation

The relays can be set up for latching (manual reset) or non-latching (automatic reset) operation.

Condition LED Relay

Normal Off Off Alarm On On Ack (No effect) On On Normal On On Ack Off Off

In this application, the meter is set up for manual reset only after the signal passes the reset point (alarm condition has cleared). Acknowledging the alarm while it is still present has no effect on either the LED or the relay. When the alarm is acknowledged after it returns to the normal state, the LED and the relay go off. Notice that the LED remains on, even after the meter returns to the normal condition. This is because, for latching relays, the alarm LED reflects the status of the relay, regardless of the alarm condition.

Acknowledging Relays

There are two ways to acknowledge relays programmed for manual reset:

1. Via the programmable front panel function keys F1-F3 (Default: ENTER key).

2. Remotely via a normally open pushbutton or active low signal wired across the F4 and COM terminals (see page 24).

When the ENTER button or the assigned digital input is closed, all relays programmed for manual reset are acknowledged.

Pump Alternation Control Applications (AltErn)

For pump control applications where two or more similar pumps are used to control the level of a tank or a well, it is desirable to have all the pumps operate alternately. This prevents excessive wear and overheating of one pump over the lack of use of the other pumps.

Up to 8 relays can be set up to alternate every time an on/off pump cycle is completed. The set points and reset points can be programmed, so that the first pump on is the first pump off.

Application #1: Pump Alternation Using Relays 1 & 2

1. Relays 1 and 2 are set up for pump alternation.

2. Relays 3 and 4 are set up for low and high alarm indication.

Set and Reset Point Programming

Relay Set Point Reset Point Function

1 30.000 10.000 Controls pump #1

2 35.000 5.000 Controls pump #2

3 4.000 9.000 Controls low alarm

4 40.000 29.000 Controls high alarm

Pump Alternation Operation

1. Pump #1 turns on when level reaches 30.000, when level drops below

10.000, pump #1 turns off.

2. The next time level reaches 30.000, pump #2 turns on, when level drops below 10.000, pump #2 turns off.

3. If the level doesn’t reach 35.000, pump #1 and pump #2 will be operating alternately.

4. If pump #1 cannot keep the level below 35.000, pump #2 will turn on at

35.000, then as the level drops to10.000, pump #1 turns off, pump #2 is still running and shuts off below 5.000.

5. Notice that with the set and reset points of pump #2 outside the range of pump #1, the first pump on is the first pump to go off. This is true for up to 8 alternating pumps, if setup accordingly.

6. Relay #3 will go into alarm if the level drops below 4.000 and relay #4 will go into alarm if the level exceeds 40.000.

7. Adding the 4 external relays, expansion module allows using the 4 SPDT internal relays for pump alternation and the 4 SPST external relays for high, high-high, low, and low-low alarm indication.

Application #2: Pump Alternation Using Relays 3 & 4

1. Relays 1 and 2 are set up for low and high alarm indication.

2. Relays 3 and 4 are set up for pump alternation.

Set and Reset Point Programming

Relay Set Point Reset Point Function

1 495 750 Controls low alarm

2 7500 6900 Controls high alarm

3 7000 900 Controls backup pump

4 6000 1000 Controls main pump

The following graphics provide a visual representation of a typical pump alternation application with high and low alarm monitoring:

1. Relay #4 turns the main pump on at 6000 gallons and turns it off at 1000 gallons.

2. With the Pump Alternation feature activated, the next time the level reaches 6000 gallons, relay #3 transfers and starts the backup pump.

68 MN301033 Rev B1

DataView™ LI55 Level Controller Instruction Manual

3. If the backup pump is not able to keep up, and the level reaches 7000 gallons, relay #4 transfers and starts the main pump as well.

4. Relay #2 trips the High Level Alarm at 7500 gallons and resets at 6900 gallons.

5. Relay #1 trips the Low Level Alarm at 495 gallons and resets at 750 gallons.

Noise Filter (filtEr)

The noise filter is available for unusually noisy signals that cause an unstable process variable display. The noise filter averages the input signal over a certain period. The filter level determines the length of time over which the signal is averaged. The filter level can be set between 2 and 199. The higher the filter level, the longer the averaging time and so the longer it takes the display to settle to its final value. Setting the filter level to zero disables the filter function.

Noise Filter Bypass (bypAss)

The noise filter bypass changes the behavior of the meter so that small variations in the signal are filtered out but large abrupt changes in the input signal are displayed immediately. The bypass value determines the minimum amount of signal change to be displayed immediately. All signal changes smaller than the bypass value are filtered or averaged by the meter. The noise filter bypass may be set between 0.1 and 99.9% of full scale.

Rounding Feature (round)

The rounding feature is used to give the user a steadier display with fluctuating signals. Rounding is used in addition to the filter function.

Rounding causes the display to round to the nearest value according the rounding selected. See examples below:

Internal Source Calibration (ICAL)

The meter is factory calibrated prior to shipment to read in milliamps and volts depending on the input selection. The calibration equipment is certified to NIST standards.

The use of calibrated signal sources is necessary to calibrate the internal source of the meter. The meter’s internal source is what allows the user to scale the meter without applying a signal.

Check calibration of the meter at least every 12 months. Each input must be recalibrated separately.

Notes:

1. If meter is in operation and it is intended to accept only one input type (e.g. 4-20 mA), recalibration of other input is not necessary.

2. Allow the meter to warm up for at least 15 minutes before performing the internal source calibration procedure.

The Internal calibration menu is part of the Advanced Features menu.

1. Press and hold the Menu button for 5 seconds to enter the full main menu. From Setup, press and hold the Menu button for 3 seconds to access the advanced features of the meter.

2. Press the Up button to scroll to the Internal calibration menu (ICAL)
