No representation or warranty, express or implied, made by any sales representative, distributor, or other agent or representative of APG which is not specifically set forth herein shall be binding upon APG. APG shall not be liable for any incidental or consequential damages, losses or expenses directly or indirectly arising from the sale, handling, improper application or use of the goods or from any other cause relating thereto and APG's liability hereunder, in any case, is expressly limited to the repair or replacement (at APG's option) of goods.
Warranty is specifically at the factory. Any on site service will be provided at the sole expense of the Purchaser at standard field service rates.
All associated equipment must be protected by properly rated electronic/ electrical protection devices. APG shall not be liable for any damage due to improper engineering or installation by the purchaser or third parties. Proper installation, operation and maintenance of the product becomes the responsibility of the user upon receipt of the product.
Returns and allowances must be authorized by APG in advance. APG will assign a Return Material Authorization (RMA) number which must appear on all related papers and the outside of the shipping carton. All returns are subject to the final review by APG. Returns are subject to restocking charges as determined by APG's "Credit Return Policy".
Display Wiring
The LPD display connects in a loop-powered configuration. A Voltage Source (V+, GND) powers the system. A 12-14 VDC MPX Level Sensor outputs a signal via a red wire to the LPD Display's input (In). The LPD Display's output (Out) via a black wire connects to the PLC/Input Device's mA input (mA In), which also receives the GND connection from the Voltage Source.
Using the LPD
The LPD features an Output Status Indicator and a Scalable Bar Graph. The device is operated using three buttons:
- Increase Button: Press to cycle upward through menu options or to increase mode setting values.
- Decrease/Power Button: Press to cycle downward through menu options or decrease mode setting values. This button also powers the display on/off.
- Enter Button: Press to enter a menu or to accept a parameter setting within a menu.
The display can show readings such as "938.0 GALLON".
Access Modes
The LPD has several operating modes that can limit or lock access to setup menus. To access the operating mode setting:
Step 1: Simultaneously press and hold the Decrease button and the Enter button for approximately 5 seconds to display a 3-digit mode access number.
Step 2: Use the Increase/Decrease buttons to change the value of the flashing digit, and the Enter button to accept the value and advance to the next digit.
Mode Options:
| Mode | Description |
|---|---|
| 000 | Full Access. All menu options are accessible, including those that may not be applicable to all LPD configurations. |
| 001 | Locks access to all setup menus. The Decrease/Power Button will turn on/off the display. The Enter button will scroll between the maximum, minimum, and the current reading. |
| 005 | All menus are hidden and all buttons are locked, except the Decrease/Power button, which will power on/off the LPD. |
| 125 | Entering Mode 125 will reset all parameters to factory defaults. |
Note: Refer to "Setting Mode Access Password" under the Sensor Label section for password information.
Menu Flow Chart
The menu structure can be navigated as follows:
Initial display shows a reading (e.g., "54321 GALLON").
Pressing ENTER leads to options: EXIT or DEFALT.
Selecting DEFALT and pressing ENTER presents YES/NO options.
Selecting INPUT and pressing ENTER leads to AVERGE.
Under INPUT, options include: 20 CAL, 4 CAL, 20 SET, 4 SET, SAM RT.
Selecting SENLAB and pressing ENTER leads to LAB 1 / LAB 2.
Selecting AdVSET and pressing ENTER leads to AUTO.
Advanced Settings (AdVSET) options include: PASSWD, UNd-Ld, OVR-Ld, bAR100, bAR 0, V HOLd, SHIFT, MASK, dEC PL.
Advanced Settings (AdVSET)
- DEC PL (Decimal Place): Defines the decimal point position within the reading.
- MASK (Digit Mask): Allows masking of the least significant digit(s) (up to 3 places), causing them to display '0' and not increment.
- SHIFT (Digit Shift): Shifts the reading to the right by dividing by 10, 100, or 1000.
- V HOLD (Value Hold): Limits the displayed reading to the 4mA and 20mA set points. When enabled, the display stops increasing/decreasing at these points even if the loop current is outside the 4mA-20mA range.
- BAR 0 (Bar Graph 0%): Defines the reading associated with 0% on the bar graph. Bars appear/disappear in 10% increments of the total span.
- BAR 100 (Bar Graph 100%): Defines the reading associated with 100% on the bar graph. Bars appear/disappear in 10% increments of the total span.
- OVR-LD (Overload): Causes the display to flash if the reading increases above the set value.
- UND-LD (Under-load): Causes the display to flash if the reading drops below the set value.
- PASSWD (Password): Sets the password required to enter the access mode setting. If set to '10AAAA', no password is required.
Sensor Labels (SENLAB) and Input Settings (INPUT)
Sensor Labels (SENLAB)
Allows the user to assign 2 custom labels that will alternate on the lower display line. If only one non-alternating label is desired, duplicate the label name in both Label 1 and Label 2.
Input Settings (INPUT)
Used to adjust how the LPD reads the analog input signal.
- AVERGE: Determines how many readings of the analog signal are averaged together for the displayed reading. Higher averaging results in smoother readings but slower response to rapid changes.
- SAM RT: Determines how often the LPD reads the 4-20mA input signal.
- 4 SET (4mA Set-point): Sets the reading associated with a 4mA input signal.
- 20 SET (20mA Set-point): Sets the reading associated with a 20mA input signal.
- 4 CAL (4mA Calibration): Adjusts the reading at the 4mA end of the input signal. Decreasing the calibration value increases the reading for a 4mA input.
- 20 CAL (20mA Calibration): Adjusts the reading at the 20mA end of the input signal. Increasing the calibration value increases the reading for a 20mA input.
DEFAULT (Reset to Factory Defaults)
Resets all settings to factory default values, including the factory 4 mA and 20 mA calibration values.
