DCA

Introduction

Moore Industries’ Direct Current Alarm (DCA) is a
highly versatile, fully adjustable device that is factory­configured to accept either current or voltage input.
The unit’s internal relays are tripped when input
deviates from a customer-set “safe” range defined by
adjustable trip points. The DCA is ideal for use in an
alarm system, where it may be used to activate a
warning device, or to drive an analog indicator.

This manual provides a brief description of the DCA,
including its physical characteristics and options; a
table of performance and operating specifications; a
set of procedures for calibrating the unit; instructions
for installation, including physical mounting and
electrical connections; and finally, information on
basic maintenance and troubleshooting.

Notes, Cautions, and Warnings are included as a
means of identifying those practices that may present
unnecessary inconveniences (notes), result in dam­age to the unit (cautions), or cause injury (warnings).

bination of single, dual, high, low, fail-safe, or non-fail­safe alarm relays. The following paragraphs describe
each of these configurations.

High Alarm/Low Alarm. A DCA configured as a high
alarm is tripped when the input increases, and
reaches a customer-set trip point. A low alarm unit is
tripped by a decreasing input that drops below a
customer-set trip point.

Figure 1 illustrates the concept.

Fail-safe/Non-fail-safe. A fail-safe unit’s relay is
energized when input is within a “safe” range, i.e. is
normal, or not in an alarm condition. When the input
goes into an alarm condition, reaching a trip point or
losing power, the relay of a fail-safe DCA is de­energized.

Conversely, a non-fail-safe unit’s relay is de-energized
when input is within the customer-specified “safe”
range, and is energized when the input reaches the
trip point setting.

Figure 1 also depicts the action of fail-safe relays.

Description

The DCA comes in either Moore Industries’ standard
(STD) or plug-in card (PC) housing.

The STD unit can be used with a variety of mounting
options, including those suitable for use with explo­sion-proof and NEMA enclosures.

PC-style DCA’s are designed for use with Moore
Industries’ multi-position card racks; the surface
mounted SMR, or the rack mounted RMR.

Both STD and PC DCA’s are available with either
single or dual alarm configurations. The relays used
are single-pole/double-throw, form C. There are a
number of input ranges and alternate relay ratings
available.

Operationally, the unit can be ordered with any com-

Controls and Indicators

Every type and configuration of DCA comes with
potentiometers (pots) to set the alarm trip points of
each installed relay. Additional pots for controlling
unit dead band are available as an option, and preci­sion ten-turn vernier scales can be used instead of
the standard pots.

Trip point pots afford full 0- to 100-percent adjustabil­ity over the unit’s specified span.

Each installed relay is wired to a front panel LED,
which lights when the relay is energized. Depending
upon the type of relay ordered, i.e. fail-safe/non-fail­safe, a lit LED can indicate either an “alarm” or a “non­alarm” input condition.

Table 1 summarizes the alarm type/LED status
options for the available types of DCA.

track of factory configuration and options for each
DCA shipped and serviced.

The example outlines the significance of each field of
information in a typical DCA model number. Refer to
table 1 for an explanation of the relay configuration
codes used.

If service information or assistance for a DCA is
needed, make a note of the unit’s model and serial
number before contacting Moore Industries’ Customer
Service Department. Our highly skilled technicians
will be happy to assist you.

STD units’ serial and model numbers are located on
an L-shaped metal tag at the top of the connection
terminal strips. On PC DCA’s, the numbers are
located on an adhesive label affixed to the side of the
front panel.

Every DCA shipped from the factory is manufactured
and tested according to Moore Industries’ exacting
standards for product quality. A bench check of basic
unit operations is recommended, however, in order to
identify any damage to the unit that may have oc­curred during shipping. This also allows the user to
effect operational adjustments to trip point settings
and unit dead band, if available.

It is recommended that the procedures in this section
be carried out at a technician’s bench or in a similar
lab environment. This is the safest means of making
adjustments to trip point values; isolated from the
intended DCA application.

The calibration of the DCA consists basically of
setting trip points and dead bands based on the
resistance across the unit contact-closure terminals
as measured by an ohmmeter. With relay contacts
closed, resistance is negligible. With relay contacts
open, resistance is infinite.

DCA

Setup for the PC DCA. There are two methods of
carrying out the calibration setup connections on the
PC DCA. Most often the unit is installed in one of
Moore Industries’ card racks, and the calibration
equipment is connected to the appropriate rack
terminal strip.

Figure 5 illustrates the PC DCA installed in the
surface mounted card rack, the SMR. Figure 6 shows
the terminal strip labeling for rack units when the DCA
is equipped with the DI Option.

As an alternative to using the card rack, individual PC
DCA’s can be checked with Moore Industries’ Pro­cess Power Supply, the PPS, equipped with its CT
Option. The CT-equipped PPS accepts the connec­tion strip of the PC DCA in a connector built into its
side panel. The PPS front panel provides access to
terminal strips similar to those used on the card
racks.

Whether using the card rack or the PPS/CT combina­tion, note that the DC power connections are not
made directly to the unit, but to the terminal strips of
either the card rack or the PPS. DC power is supplied
to the DCA at its pins 8 and 9

NOTE

The “UPPER” and “LOWER” labeling used

on the DCA is for reference purposes only.

The trip point pots allow for adjustments through 100­percent of span. It is therefore possible for the
connections to the “LOWER” labeled alarm section to
be configured as a “high alarm”, and the “UPPER”
section to be configured as a “low alarm”.

NOTE

The LED’s DO NOT always indicate an

alarm condition; rather, they light to show

that their complimentary relay is ener-

gized. It is possible for a DCA to be

configured such that the LED’s are lit

when input is in a “non-alarm” state.

Setup of DCA’s in Explosion-proof Enclosures.

The DCA in an explosion-proof enclosure (EX) in­corporates a modification of the STD housing where
the connection terminals are replaced with pins on the
unit bottom panel. These pins are inserted in a
terminal block permanently mounted inside the base
of the explosion-proof enclosure.

To effect the calibration connections, unscrew the top
of the enclosure and pull the DCA up and out of the
enclosure base, exposing the terminal block. Figure 7
shows the block and its labeling. Figure 8 shows the
labeling used for units equipped with the DI Option.

Use the appropriate terminal locations figure to
connect the calibration equipment to the terminal
block in the enclosure base. Then re-connect the
DCA by aligning the pins on the bottom of the unit
housing with the holes in the terminal block. Press
down until the unit is seated firmly in the enclosure
base.

CAUTION

The EX DCA housing fits into the terminal

block in its correct orientation only. Note

the position of the connection “key”.

Attempting to “force” the unit in when the

pins are not aligned with the correct holes

will bend the pins.

Basic Calibration Hookup. Use the terminal loca­tions figure that is appropriate for the type of DCA
being checked, and connect the equipment described
in the calibration equipment table as shown in the
calibration hookup diagram, figure 9.

Set all low alarm pots fully counterclockwise. DCA
pots are equipped with slip clutches to prevent
damage in the event of over-turning. A slight change
in torque may be felt when a wiper stop is reached. If
unable to sense the stop, set pot 15 turns counter­clockwise.

Special Considerations for AR-equipped DCA’s.

Units equipped with the AR Option are factory-set for
specific alarm delay times ranging from 1 to 30
seconds (refer to Options listing). The AR is set and
fully calibrated according to customer requirements
before unit shipment.

The delay in an AR-equipped DCA’s transition from
normal to alarm condition makes the calibration of trip
points difficult, and a temporary disabling of the option
is therefore recommended during the calibration
procedures.

To defeat the AR Option, diodes on PC1 of the DCA
must be shorted. There is a diode for each installed
relay.

DCA’s in the STD housing must be partially disas­sembled to access the AR diode(s). See figure10.
Figures 11 and 12 show the location of the diodes on
the various types of AR-equipped DCA.

Access to the AR diode(s) on PC-style DCA’s may be
difficult if the unit being calibrated is already installed
in its rack. Moore Industries offers an Extender Card
accessory for calibrating units under these circum­stances.

Calibration Procedures

Before beginning the actual calibration of the DCA,
check the unit’s model number to verify that the
correct power supply and input simulator is being
used. Make sure that the appropriate connections are
made as shown in the figures of the preceding
section.

Using the Calibration Procedures. The Calibration
Procedures section is divided into subsections that
describe first low alarm, then high alarm trip point
setting. The procedure for calibrating the DCA dead
band, for units equipped with the AD Option, should
be conducted after the trip points are set.

If the DCA to be calibrated is equipped with the TT
Option, skip to and complete the procedure in the
section entitled “Calibrating DCA’s Equipped with the
TT Option”.

Setting Low-Alarm Trip Points. Remember that the
“UPPER” and “LOWER” labeling on the DCA is for
reference purposes only. The DCA can be ordered
without low alarms, as in a “high/high” configuration.
Dual alarm units can be ordered with either one or
both relays configured as low alarms, and DPDT­equipped DCA’s may be configured with any combina­tion of high/low alarms.

Refer to the unit’s model number to determine the
alarm configuration, and perform the following proce­dure for each installed low alarm.

1. Check model number to verify correct power
input, and apply 117 or 240 Vac; 24 or 45 Vdc, as
appropriate.

2. Make sure that ohmmeter in calibration setup is
connected to appropriate -NO or -NC terminals, as
desired.

3. Apply 100% of application’s input span (current or
voltage, as appropriate) to DCA.

If low alarm is configured as fail-safe, L1 in model
number, verify that appropriate LED for that alarm
is lit. LED for non-fail-safe low alarm, L2 in model
number, will not be lit.

4. Note ohmmeter reading.

In a low alarm, 100% input is a non-alarm condi­tion. If connected to XNO and COM terminals (
= U or L, UPP or LOW; NO = normally open),
Resistance across the terminals in a fail-safe
alarm is zero. In a non-fail-safe alarm resis­tance will be near infinite.

If connected to XNC and COM terminals, resis­tance is infinite in fail-safe, zero in non-fail-safe
alarms.

5. Set input to desired low alarm trip point level.

6. Turn appropriate low alarm adjustment pot (may
be labeled “UPPER” or “LOWER”) slowly clock­wise. Observe LED and ohmmeter, and stop
turning at exact point where relay changes state.

Vary pot setting slightly above and below trip
point to “zero in” on exact setting.

If low alarm is configured as fail-safe, L1 in model
number, verify that appropriate LED for low alarm
is not lit. LED for non-fail-safe low alarm, L2 in
model number, will be lit.

7. Verify desired setting by varying input above and
below trip point level (from step 6) and observing
both LED and ohmmeter to confirm change of
relay state at, and below trip point setting.

NOTE

Units equipped with any Manual Reset

Option have external push buttons that

must be pressed to reset the relays once

they have been tripped.

Setting High-Alarm Trip Points. Remember that the
“UPPER” and “LOWER” labeling on the DCA is for
reference purposes only. The DCA can be ordered
without high alarms, as in a “low/low” configuration.
Dual alarm units, on the other hand, can be ordered
with either one or both relays configured as high
alarms.

3. Apply 0% of application’s input span (current or
voltage, as appropriate) to DCA.

If high alarm is configured as fail-safe, H1 in
model number, verify that appropriate LED for that
alarm is lit. LED for non-fail-safe low alarm, H2 in
model number, will not be lit.

4. Note ohmmeter reading.

In a high alarm, 0% input is a non-alarm condi­tion. If connected to XNO and COM terminals
(X= U or L, UPP or LOW; NO = normally open),
Resistance across the terminals in a fail-safe
alarm is zero. In a non-fail-safe alarm resis­tance will be near infinite.

If connected to XNC and COM terminals, resis­tance is infinite in fail-safe, zero in non-fail-safe
alarms.

5. Set input to desired high alarm trip point level.

6. Turn appropriate high alarm adjustment pot (may
be labeled “UPPER” or “LOWER”) slowly clock­wise. Observe LED and ohmmeter, and stop
turning at exact point where relay changes state.

Vary pot setting slightly above and below trip
point to “zero in” on exact setting.

If high alarm is configured as fail-safe, H1 in
model number, verify that appropriate LED for that
alarm is not lit. LED for non-fail-safe high alarm,
H2 in model number, will be lit.

Refer to the unit’s model number to determine the
alarm configuration, and perform the following proce­dure for each installed high alarm.

1. Check model number to verify correct power
input, and apply 117 or 240 Vac; 24 or 45 Vdc, as
appropriate.

2. Make sure that ohmmeter in calibration setup is
connected to appropriate -NO or -NC terminals, as
desired.

7. Verify desired setting by varying input above and
below trip point level (from step 6) and observing
both LED and ohmmeter to confirm change of
relay state at, or above trip point setting.

NOTE

Units equipped with any Manual Reset

Option have external push buttons that

must be pressed to reset the relays once

they have been tripped.

Page 16

DCA

Setting the Dead Band. See figure 1 for a graphic
representation of the DCA dead band. The dead band
may be thought of as an “area” around a trip point in
which the alarm will not reset.

In a scenario using a high-alarm DCA as an example,
the unit will signal an alarm at its trip point, and will
continue to signal an alarm as long as the input is
above that point.

Without an adjustable dead band, the relay will reset
when the input drops below the trip point. When
equipped with the AD Option, however, no reset will
occur until the input continues to drop to the dead
band setting, presumably some percentage of span
below the trip point.

To set the DCA dead band:

1. Make sure dead band pots are turned fully
counterclockwise. Set trip points for installed
alarms as described in preceding section. Con­nect ohmmeter to UPPER alarm section to set
UPPER dead band, or to LOWER section for
setting LOWER dead band.

For Example

A single, high-alarm DCA rated for 4-20 mA input is
required to have a 25% dead band around its 14 mA
trip point setting. To calculate the input level needed
to set the desired dead band, subtract 25% of 16 mA
(span) from 14 mA:

The result, 10 mA, is the level of input to be applied in
step 2. The DCA in this example will signal an alarm
condition when the input reaches or exceeds 14 mA,
but will not reset until the input drops below 10 mA.

Calibrating TT-equipped Units. Lockable, multiturn
trip point adjustment pots on the front panel of each
TT-equipped DCA are set at the factory so that “0.00”
on the dial is equal to 0% of the application’s rated
input span. “10.00” is equal to 100% of span. The
accuracy of these settings is ±0.5% of the rated
span.

:

Trip point setting in mA = 14

– 25% of input span in mA = 16(0.25)

14 – 4 = 10

2. Apply input at the dead band setting level.
Typically, this will be lower than trip point for high
alarms, or higher than trip point for low alarms.

3. Turn appropriate dead band pot slowly clockwise,
observing LED and ohmmeter.

4. Set pot (stop turning) at exact point at which relay
changes state.

5. Verify desired setting by varying input above and
below trip point, observing both LED and ohmme­ter to confirm appropriate change of relay state.
Unit will “trip” at trip point setting, and will not
reset until input returns past dead band setting.

The DCA dead band can be expressed as a percent­age of the unit’s factory-configured span.

Calibration of DCA’s with this option consists of two
procedures. First, the internal, Full-Scale Adjust
(FSA) potentiometer(s) must be set (this involves
some disassembly of the STD DCA). Then, the unit
zero, trip points, and dead band (if so-equipped), must
be set.

Figure 13 shows the location of the STD DCA FSA
potentiometers. Figure 14 shows the location of the
pots on the PC-style unit. Refer to figure 10 when
disassembling the unit in STD housing, and refer to
figures 13 or 14 while executing the procedure.

NOTE

The following procedure assumes that the

DCA being calibrated has its “UPPER”

alarm section configured as a high alarm,

and its “LOWER” alarm section configured

as a low alarm. If this is not the case for

your DCA, interchange references to

“UPPER” and “LOWER”, as appropriate.

1. With the hookup described in the Calibration
Setup Section complete, disable AR Option as
described in section titled “Calibrating AR­equipped DCA’s”. Connect ohmmeter to “UP­PER” alarm terminals first.

2. Verify that all pots are set fully counterclockwise,
to 0.00.

NOTE

Steps 3 through 10 apply to high alarms.

Skip to step 11 to calibrate the ten-turn

dials on low alarms.

3. Apply 0% of appropriate input from application.
Refer to unit’s model number and specifications
listing in table 2.

4. Turn ZERO pot clockwise until both “UPPER” and
“LOWER” alarms trip.

5. Apply 100% input to setup.

6. Turn “UPPER” and “LOWER” pots clockwise to

10.0 setting.

7. Turn internal FSA pots fully counterclockwise.
High alarm will change state. Disregard low alarm
at this time.

8. Turn FSA pot for “UPPER” alarm slowly clock­wise, observing ohmmeter and appropriate front
panel LED.

9. Set FSA pot (stop turning) at exact point at which
high alarm is tripped. If high alarm is configured
as fail-safe, H1 in the unit model number, verify
that appropriate LED for high alarm is not lit. The
LED for a non-fail-safe high alarm, H2 in the
model number, will be lit.

12. Turn “LOWER” FSA pot slowly clockwise, observ­ing ohmmeter and appropriate front panel LED.

13. Set FSA pot (stop turning) at exact point at which
low alarm is tripped.

If low alarm is configured as fail-safe, L1 in the
unit model number, verify that appropriate LED for
low alarm is not lit.

The LED for a non-fail-safe low alarm, L2 in the
model number, will be lit.

14. Alternate the input between its rated 0 and 100%
level, verifying the setting of the unit’s front panel
pots (0.00 at 0% input, 10.00 at 100% input).
Readjust both FSA pots as necessary.

Calibrating DA -equipped Units. If ordered, the
Deviation Alarm Option allows the user to set alarm
trip points based on the difference between two
inputs. This difference is expressed as a percentage
of total input span, and unit relays are “tripped”
whenever process input varies, more than (high alarm)
or less than (low alarm) the set percentage.

To calibrate DA-equipped DCA’s, a second input
source will be needed. Refer to table 3, and use two
of the appropriate sources as specified.

Refer to figures 2 through 8 as appropriate, to deter­mine which of the unit terminals is used for the
second, reference input connection.

Finally, refer to the setup shown in figure 9, and add
the connection for the second input source as follows:
“+REF” is used for positive reference input, and the
negative connection for both inputs is common, the “–
IN”.

To calibrate DA-equipped DCA’s:

10. Disconnect ohmmeter, and reconnect it to
“LOWER” alarm section of DCA.

11. With input at 100%, and ohmmeter connected to
“LOWER” alarm section of unit, turn appropriate
“LOWER” FSA pot fully clockwise. Note that low
alarm trips.

1. With setup complete as described in preceding
paragraph, and all pots set fully counterclockwise,
determine percentage of rated input span that is
to serve as difference between reference input
and input #2.

2. Set reference input to 50% of rated span.

Page 19

DCA

3. Set input #2 to desired percentage above or below
reference.

4. Set trip points as appropriate, using UNC pot for
UPPER normally closed alarm, UNO pot for
UPPER normally open; LNC for LOWER normally
closed, and LNO for LOWER normally open.
Base settings on input #2.

Units factory-configured as high alarms will “trip”
when input #2 exceeds the desired difference.
Low alarms “trip” when input #2 falls below
desired difference.

For Example:

A DA-equipped DCA is rated for two, 4-20 mA inputs
(“2X” in the model number). The application calls for
an alarm condition when input #2 varies more than
25% of span from the reference input.

Span = 16 mA

25% of 16 = 4 mA

The reference input is set to 50% of rated span, or 12
mA. Input #2 is set 25% higher, 16 mA.

Installation

Installing the DCA is typically accomplished by
physically mounting the unit, then effecting the
electrical connections.

Mounting

Figures 15 and 16, respectively, show the outline
dimensions of the DCA in the STD and the PC
housing styles. The drawing of the STD housing
includes the dimensions of the U-bracket, typically
included with that type of DCA, and also of the side
housing used for DCA’s equipped with the DPDT
option.

Always try to install the DCA in an area relatively free
of dust, excessive moisture, or corrosives.

Contact your Moore Industries Sales Representative
for information on other types of DCA housings,
enclosures, and mounting hardware.

The trip point pots are turned clockwise until relays
change state.

Regardless of how the reference input is varied, from
4 to 20 mA, as long as input #2 is likewise varied at a
50% offset, the alarms are not “tripped”.

However, if the reference is at 12 mA and input #2 is
at 20 mA, the high-alarm relay will indicate an alarm
condition. Likewise, if the reference is at 12 mA and
input #2 is at 14 mA, the low-alarm relay will indicate
an alarm.

Making Electrical Connections

Figure 17 illustrates the installation hookup for the
unit. Refer to the terminal location figures in the
Calibration Section when making the electrical
connections associated with installing the DCA.

Though there is no special wiring required for standard
connections, the use of shielded, twisted wiring is
recommended for all low-level signals, or where
connecting leads are run close to other services such
as power wiring. Ground the shield wire as close to
the DCA as possible in the installation.

When making the electrical connections for units in
explosion-proof enclosures, route the wiring through
the conduit hubs in the enclosure with enough slack
to reach the appropriate terminal.

Units in oil- or water-tight NEMA enclosures require
the use of Myer Scru-Tite (or equivalent) fittings to
maintain the enclosure integrity when routing wiring
conduit to or from the DCA.

WARNINGS

Do not apply power to the DCA until all

connections are secure. The uncovered

power input terminals of ac-powered STD

DCA’s present an electric shock hazard.

Always turn off the power to the unit

before servicing.

Maintenance

Once the DCA is properly calibrated and installed, it
will operate indefinitely. No further adjustments
should be necessary, unless the unit is moved, or the
process input changes.

It is recommended that the unit terminals be checked
periodically for signs of oxidation or looseness.

If a problem develops with the performance of the
DCA, remove the unit from service and recalibrate.
Refer to the Calibration Section of this manual for
instructions.

Any units found to be performing below specifications
after a recalibration should be returned to the factory
immediately. Instructions for unit return can be found
on the back cover of this manual.

SUPPLEMENT

To Manual No. 192-701-00 G

Purpose

This supplement is being distributed to users of
Moore Industries' Direct Current Alarm (DCA) to in­form them of corrections/additions to the current
manual since its release date. These changes will
be incorporated in the manual during its next revi­sion.

Corrections

The wording of the second paragraph of step 4 of the
"Setting Low-Alarm Trip Points" (page 14) and "Set­ting High-Alarm Trip Points" (page 15) calibration
procedures should read:

In a low alarm, 100% input is a non-alarm condi­tion. If connected to XNO and COM terminals (X =
U or L (upper or lower); NO = normally open). Resis­tance across these terminals in a fail-safe alarm is

terminal labeling is true when power is removed from
the unit or when the unit is operating and the LED is
NOT lit. Since each LED illuminates only while the
corresponding relay is
not lit its corresponding relay is de-energized.

So, regardless if the DCA is configured for fail-safe
or non-fail-safe operation, each relay's normally-open
or normally-closed contact states are true as labeled
only when the relay is de-energized.
