Installation: Intrinsically Safe Sensing Circuits
Thisbulletinshouldbe usedby experiencedpersonnel asa guideto theinstallation ofthe SeriesDMS-470/570 alarm
panels. Selection or installation of equipment should always be accompanied by competent technical assistance. We
encourageyou tocontact Warrickorits localrepresentative iffurtherinformation isrequired.
Important
Before proceeding to install and wire the control panel,
read and thoroughly understand these instructions.
When the Series DMS 470/570 Monitoring Panel is installed according to these instructions, the panel will provide
intrinsically safe sensing circuits for interface into Class I, II. Division 1, Groups C, D, E, F and G hazardous loca-
tions. Electrical equipment connected to Series DMS 470/570 Monitoring Panel should not exceed maximum ratings
markedon product.
Mounting Location
The control must be situated in a non-hazardous area where an explosive atmosphere will not exist at any time.
Wiring: General Information
1. Intrinsically safe wiring must be kept separate from non-intrinsically safe wiring.
2. Intrinsically safe and non-intrinsically safe wiring may occupy the same enclosure or raceway if they are at least 2
inches(50mm) apartand separatelytied down.Inside panels,field wiringterminals forintrinsically safecircuits
must be separated by at least 2 inches (50 mm) from non-intrinsically safe terminals.
3. For sensor wiring, use #14 or #16AWG type MTW orTHHN wire. By using these wire types in conjunction with
thefollowing distancerecommendations, youwillnot exceedthe maximumcapacitance forfieldwiring.
Use Table 1 as a guide for maximum wire runs.
4. Intrinsically safe terminals can be connected to any non-energy generating or storing switch device such as a
pushbutton, limit or float type switch or any Warrick electrode and fitting assembly.
5. Alljunction boxesand fieldwireterminations shouldbe waterproof.Referto appropriatesensor instructionsfor
details on how to install sensors.
6. An approved seal should be used at the point where the intrinsically safe control circuit wiring enters the hazard-
ousarea.
7. Foradditional guidanceon“Hazardous LocationInstallation”and “IntrinsicallySafeDevices”, consult ANSI/ISA
standard RP12-6 orNEC articles500-516.
SensorWiring
Sensors: Wire the sensor devices to the Series DMS 470/570 Monitoring Panel as shown in figure 3-1 to 3-4. (A
separate rigid metallic conduit must be used to enclose the conductors of the intrinsically safe sensor
circuit. A conduit hub is provided on the bottom side of the enclosure for intrinsically safe wiring.)

Control Panel Settings
Before putting system into operation, DIP switches and potentiometers (set point) must be set to correctly match the
type of sensor you are using. (Ref to Table 4-1). The DIPswitches and potentiometers are located above the sensor
terminal strip. (Figure 4-1)
Setting the DIP Switches
Table 4-1describes applications vs. DIP switch settings. Each channel will have its own setting corresponding to the type of
sensorbeing used.

Adjusting the Set Point Potentiometer
DIP Switch Set In Inverse (ON) Mode: When using a channel in Inverse(ON), there is no need to adjust the potentiom-
eter. The channel is automatically set to the maximum sensitivity.
DIP Switch Set In Direct (OFF) Mode: Turn the potentiometer clockwise until it reaches the end of its rotation. Do not
force the rotation. When the potentiometer is adjusted to this position, it is set to the maximum sensitivity. When using
SVP-2 Vapor Sensors, it may be necessary to reduce this sensitivity. Continue with the following instructions.
The Following AdjustmentApplies only to those channels using an SVP-2 Vapor Sensor.
This adjustment will allow the alarm point to be set at a level just higher than the existing background contamination, thus
only indicating a potential new leak or spill condition.
CAUTION:As the Vapor sensor reacts over time (Months) to background (Existing) contamination, a false alarm
may occur. If this occurs, repeat the adjustment procedure.
1. With all appropriate potentiometers set to fill clockwise position, apply power to the panel and observe the state of the
indicator lights. Silence the audible alarm if necessary.
2. Upon power-up, no warning lights (audible alarm) should be on. If the warning lights are lit, proceed to step 3. Starting
withthe firstchannel usinga vaporsensor,turn thepotentiometer counter-clockwiseuntil thewarninglight turnson.
(silencethe audiblealarm) Turnthepotentiometer clockwiseuntil thealarmlight turnoff. Turnthepotentiometer an
additional1/8 turn.Repeatthis procedureforthe remainingchannelsusing vaporsensors.
3. If an alarm light remains lit, determine which channel is activated. Check the position of the DIP switch for the sensor
beingused onthat channel.Checkthe sensorwiring. Checkfor a truefault condition.Refer totroubleshootingguide for
furtherdetails.

HOT lead to the L1 terminal, NEUTRAL lead to the L2 terminal and EARTH GROUND lead to the “G”Terminal.
Grounding
Terminal “G” on the supply line/load side terminal strip is a redundant system ground terminal and must be connected to
theearth groundbuss ofthe panel’sACsupply linefeeder.
Remote Alarm Contact
A set of SPDT dry contacts activates on fault when any one of the four (4) channels alarms. Using the conduit hub on
the top of enclosure, wire contacts to remote alarm or indicator, if applicable (terminals 7,8 and 9). For low voltage
circuits, wiring should not be run in the same conduit as high voltage circuits. Conduit should be teed immediately after
leavingenclosure.
Optional Auxiliary Contact Board
A SPDT auxiliary set of contacts are available for interfacing to remote alarms, computers, tank gauging systems, etc.
Oneset ofcontacts perchannelare provided.Wire throughconduit hub ontop ofthe enclosure.(SeeFigure 9-1)

Operation Instructions
Panel Operation:
Withsensors wiredto controlpaneland powerapplied,the normallight (yellow)shouldbe lit.Individual warning
lights(amber) areprovided foreach channel. Ifa sensordetects afaultcondition, thenormal lightwill de-
energize.Theappropriate warninglightwill thenenergize andtheaudible alarmwillsound.Tosilence the
alarm, push the SILENCE pushbutton. The WARNING light will remain lit until the fault condition is cleared. If a
secondfault occursbefore thefirstfault iscleared, theappropriate WARNINGlightwill energizeand thealarm
will sound. Each successive fault will cause the alarm to sound.
ATEST button is supplied to test the circuitry in the panel.To perform a test, push the TESTpushbutton and
hold. The NORMALlight will go off.All WARNING lights in that bank will light and the alarm will sound.
Releasing the TEST pushbutton will return the system to a normal condition.
All panels contain a master fault contact, which will activate if any one of the channels sees a fault condition.
This can be used to trigger a remote alarm or cash register. The master fault contact will reset when the
SILENCEpushbutton ispressed.
If optional auxiliary contacts are used, a SPDTdry contact is provided for each channel.To reset these contacts,
the fault condition must be cleared.
Fuel/ Water Pushbutton Operation:
If the audible alarm is energized, it can be silenced by momentarily depressing the SILENCE pushbutton.
However, to determine if this is a FUELor WATER leak, continue with the following instructions.
1.WATER PUSHBUTTON: (When audiblealarm isalreadysilenced.) Momentarilydepress theWATER pushbutton.If,after
release of the button the audible alarm energizes, this indicates a water leak. The audible alarm can be silenced again by
depressing the SILENCE pushbutton. If pushing the fuel button has no effect, continue to step 2.
2.FUEL PUSHBUTTON: (When audibleisalready silenced.)Momentarilydepress thefuel pushbutton.Ifafter releaseofthe
button the audible alarm engergizes, this indicates a fuel leak. The audible alarm can be silenced again by depressing the
SILENCEpushbutton.
Troubleshooting Guide:
A test button is used on all models to test the control panel. If the system is powered up and there are no fault conditions, the
normal contact should be lit. The warning lights and alarm should be de-energized. On pushing the test button, the normal
lights go off, all warning lights in that bank should light up and the alarm should sound. Push the silence pushbutton to de-
energize the alarm. Releasing the test pushbutton should return the system to a normal condition.
If a WARNING light has been activated and a true fault condition is not found:
1. Recheck position of DIP switch (Figure 4-1,Table 4-1). If correct continue.
2.If theDIPswitch isinthe InverseMode(“ON”)position,removingthesensorwiring attheterminal blockshouldde-
activatethealarm.Shortingtheterminal pointsshouldactivate thealarm.Ifthisdoesnothappen, replacetheelectronic

3.IftheDIPswitchisintheDirect Mode(“OFF”)position, removingthesensor wiringatthe terminalblockshould

tronicmodule.
