Series 4000 Recording Ammeter Instruction Manual

Measurement Features

Recording ammeters have one or more of following measurement features:

 AC Current Range: Measures alternating current, provided in standard

range of 0-5 amperes at 50-60 Hz.

 Optional Test Terminals: Some models provide test terminals to simplify

calibration and service procedures.

 Pen Lock: The measuring element includes a locking mechanism that you

can be set to secure the meter movement and pen system for shipment.

 Pen Damping: Magnetic damping minimizes rapid pen fluctuation caused

by measured variables having a noise or oscillation component.

1.2 Theory of Operation

Recording ammeters employ a meter assembly that positions the pen on the

chart. See Figure 1-2.

Figure 1-2. Meter Assembly (Internal View)

1-2 General Information Revised Aug-11

Series 4000 Recording Ammeter Instruction Manual

Revised Aug-11 General Information 1-3

The meter assembly contains a coil, a fixed-iron pole piece, and a movable-

iron pole piece that pivots freely on a shaft. When no AC is present at the input

terminals, a return spring keeps the two pole pieces together. When an AC

input is applied to the coil circuit, the coil generates a magnetic field that

causes the moving pole piece to move away from fixed pole piece. Since the

moving pole piece is attached to the shaft of the pen arm, it will cause the pen

to record the amount of movement or input change on the chart of the recorder.

Attached to the rear of the output shaft is a metal vane that pivots between the

gap of a circular magnet. In a static condition, the magnetic fields concentrated

at the gap have no effect on the vane. When a movement of the output shaft

occurs due to a change of input level, the magnetic field at the gap generates

eddy currents within the vane. These eddy currents, in turn generate counter

fields that oppose the fixed field of the circular magnet. These counter fields

partially inhibit motion of the vane and result in a slower but more uniform

pen tracking. A counterweight assembly attached to the pen arm shaft

functions as a counter balance to minimize mechanical drag.

1.3 Model Identification

A data plate affixed to the recorder provides the model and serial numbers, and

the measurement range of each pen. Other pertinent data may also be included.

Always refer to this plate when requesting support.

The model number listed on the data plate identifies the features of the

instrument:

Chapter 2 – Installation

This chapter discusses the installation procedures for the Series 4000

Recording Ammeter.

2.1 Unpacking the Instrument

Carefully remove all protective cushioning material, cardboard guards,

and shipping tape. Check the accessory mounting kit (if included) for

completeness.

The ammeter ships with its pen secured in a fixed position. Remove any

tape, elastics or packing material as required. Do not apply excessive

force to mechanisms while unpacking as calibration errors or damage

may result.

2.2 Selecting a Location

Series 4000 instruments are intended for general-purpose indoor

installations. When choosing a site for the instrument, select one that is

convenient to both the process and operator. Avoid areas with high levels

of dust or corrosive fumes. Avoid installation sites subject to severe

vibration or mechanical shock.

Make sure the instrument operates within its stated temperature and

humidity range (see Chapter 6, Specifications). If ambient conditions

exceed the stated temperature and humidity, errors and poor performance

may result. Prolonged operation under extreme ambient conditions may

also cause instrument failure.

Warning

Do not install or operate these instruments in environments

containing combustible air-borne particles or flammable gases.

These instruments contain electrical devices, which could (under

certain conditions) generate sparks and result in flash fire or

explosion.

2.3 Installing the Instrument

Before installing the instrument, make sure that the area provides good

illumination for the operator. Allow sufficient clearance for the door to

swing open and for any back or bottom connections to enter the

instrument.

Install the instrument so that it is level on both its horizontal and depth

axis. This ensures that the instrument provides its maximum

performance.

Figure 2-1 shows the overall mounting dimensions for various types of

instruments.

Chapter 3 – Field Wiring

This chapter discusses field wiring for the Series 4000 Recording

Ammeter.

3.1 Electrical Termination

Recording ammeters use internal electrical terminal connections. Models

with internal connections have the wiring terminals located inside the

case on the ammeter assembly and on the chart drive.

3.1.1 Customer Connection Plate (CCP)

All models are furnished with a CCP (see Figure 2-3 in Chapter 2). The

CCP has four 7/8” holes. CCPs are factory-furnished with either

protective plugs or electrical binding posts.

3.1.2 AC Wiring Notes

Instruments are factory-configured with the customer-specified current

range.

Make sure that voltage listed on the instrument data plate conforms with

the local power source before making any connections. Using the wrong

supply voltage can result to improper operation or instrument burnout.

Warning

Do not attempt to connect live wires to the input terminals. The

instrument AC power source must be turned off to prevent

electrical shock.

Recorders are furnished with a green grounding screw inside the case

(typically found below the chart plate on the base). It is essential that this

screw connects to an approved earth ground to provide maximum safety

for users.

Warning

Electrically powered instruments must be properly grounded to

protect users from electrical shock and possible fatal injury.

Grounding should be performed in accordance with the National

Electrical Code, ANSI/ISA standard S82.01, S82.02 and S82.03

and local regulations.

If the instrument is wired for an AC power outlet, a three-pronged plug is

required. The wire coming from the green-coded prong of the plug must

connect to the green grounding screw of the instrument.

If AC wiring is brought in through a metal power conduit, then a separate

wire from the ground point must connect to the green grounding screw of

the instrument.
