PAM59
Accumulating Module
Instruction Manual
1.0 INTRODUCTION
These instructions refer to the above model. Supplementary
sheets are attached if the unit has special options or features.
For detailed specifications, see page 4 or refer to the Data
Bulletin. All ADTECH instruments are factory calibrated and
supplied with a label detailing the calibration. Adjustments are
normally not necessary. A simple check should be performed
to verify calibration before installation to ensure that it matches
the field requirement.
2.0 GENERAL DESCRIPTION
The ADTECH PAM 59 is a Non-Isolated Pulse Accumulating
Module that integrates/totalizes the number of pulses from
primary sensors to a standard control signal output such as
4-20 ma de.
The output is a true current source and provides process
signals such as 4-20 ma, 0-1 ma, 0-1 O ma, 1-5 ma and
10-50 ma de or alternatively, a voltage signal of 5 vdc full
scale. Other current and voltage
Inputs/Outputs
(l/0)
are
available as specified on the Data Bulletin.
3.0 INSTALLATION
The instrument is supplied in a general purpose enclosure as
standard.
NEMA
4, 7 or 12 and plug in chassis enclosures are
optionally available. Installation area/location must agree with
the supplied instruments including operating temperature and
ambient conditions.
Mounting
Refer to the appropriate outline drawing for mounting and
clearance dimensions. The instrument is surface mounted
with two #10-32 screws on 8.00 inch centers.
Electrical Connections
The wire used to connect the instrument to the control system
1/0,
should be a twisted pair(s) and sized according to normal
practice. Shielded cable is not normally necessary (if used,
the shield must be grounded at the input of the ADTECH
instrument and left floating at the sensor).
A 12 position barrier terminal block with #6-32 screws and
3/8" spacing is provided for
1/0
and power connection.
A housing ground terminal marked G is also provided.
Controls
Multiturn ZERO and
SPAN
controls are provided to calibrate
the instrument. The multiturn controls are accessible through
the instrument front panel and are clearly marked for ease of
use.
4.0 MAINTENANCE
These instruments are electronic and require no maintenance
except periodic cleaning and calibration verification. If the unit
appears to be mis-operating it should be checked as installed
per section 6.0 or removed for a bench check per sections
6.0-7.0. MOST problems are traced to field wiring and/or
associated circuits. If the problem appears to be with the
instrument, proceed to sections 6.0 and 7.0.
5.0 CONNECTIONS
Standard connections are shown below and on the instrument
face plate, Data Bulletin or on attached supplementary sheets.
