Analog Panel Meter Instruction Manual

INTRODUCTION

The APM is a multi-purpose, easy to use rate/totalizer ideal for flow rate, total, and

control 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 specific operation.

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, F4, is

standard.

A fully loaded APM rate/totalizer meter has the following: four SPDT relays, 4-20 mA

output, and two 24 VDC power supplies. The APM capabilities may be enhanced by

adding the following external expansion modules: four SPST relays (creating an eight-

relay rate/totalizer), two digital I/O modules with four inputs and four outputs each, and

RS-232 or RS-485 communication adapters.

The eight relays can be used for alarm indication or process control applications. The

4-20 mA isolated output, Modbus RTU serial communications, and digital I/O options

make the APM an excellent addition to any system.

General

DISPLAY Upper display: 0.6" (15 mm) high, red LEDs

DISPLAY

ASSIGNMENT

Display lines 1 & 2 may be assigned to rate, total, grand

total, alternate (rate/total, rate/grand total, rate/units,

total/units, and grand total/units), set points, max/min, units

(line 2 only), and Modbus input. Additional displays are

available if parameter total is off, and parameter d-SCAL

is on: gross, alternating gross/net, PV1, PV2, and PCT

(refer to MPM instruction manual found on www.dwyer-

inst.com).

PROGRAMMING

METHODS

Four front panel buttons, digital inputs, or PC and Panel

Meter Pro software.

NOISE FILTER Programmable from 2 to 199 (0 will disable filter)

FILTER BYPASS Programmable from 0.1 to 99.9% of calibrated span

RECALIBRATION All ranges are calibrated at the factory. Recalibration is

recommended at least every 12 months.

MAX/MIN

DISPLAY

Max/min readings reached by the process are stored until

reset by the user or until power to the meter is turned off.

PASSWORD

Three programmable passwords restrict modification of

programmed settings and two prevent resetting the totals.

Pass 1: Allows use of function keys and digital inputs

Pass 2: Allows use of function keys, digital inputs and editing set/reset points

Pass 3: Restricts all programming, function keys, and digital inputs.

Total: Prevents resetting the total manually

Gtotal: Prevents resetting the grand total manually

NON-VOLATILE

MEMORY

All programmed settings are stored in non-volatile memory

for a minimum of ten years if power is lost.
