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.
