INSTALLATION

Mounttheinstrumentinalocationthatwillnotbesubjecttoexcessivetemperature,shock,

or vibration. All models are designed for mounting in an

enclosedpanel.

Selectthepositiondesiredfortheinstrument onthepanel.

If more than one instrument is required, only two units can

bemountedcloselytogether,eitheroneabovetheotheror

sideby side. When mounted together,the mounting collar

will require modification by removing the inside tab from

each collar.

Prepare the panel by cutting

and deburring the required

opening.

From the front of the panel,

slide the housing through the

cut out. The housing gasket

shouldbe againstthehousing

flange before installing.

From the rear of the panel slide

ing. Hold the housing with one

hand and using the other hand,

slightly compressed. The ratch-

ets will hold the mounting collar

and housing in place.

INPUTWIRING

ALARMTYPE AND ACTION (if present)

Caution: In any critical application where failure could cause expensive

product loss or endanger personal safety, a redundant limit controller is

required.

When setting an alarm value for an absolute alarm (ALt = AbS), simply set the value at

which the alarm is to occur.

When setting the alarm value for a deviation alarm (ALt = dE), set the difference in value

from the Set Point (SP) desired. For example, if a low alarm is required to be 5 degrees

belowtheSP,thensetALLoto-5.Ifahighalarmisrequired20degreesabovetheSP,then

setALHi to+20.IfSPis changed, thealarmwillcontinuetoholdthesamerelationshipas

originally set.

The diagram at the top of the next page shows the action and reset functions for both

absolute and deviation alarms.

When Alarm Power Interrupt, ALPi, is programmed ON and Alarm Reset, ALrE, is

programmed for Hold, the alarm will automatically reset upon a power failure and

subsequent restoration if no alarm condition is present.

as if a power up took place by pressing both the INDEX and ENTER keys for 5 seconds.

Warning:Resetting a high alarm inhibit will not cause an alarm to occur

if the Process Value does not first drop below the high alarm setting. Do

not use the Alarm Inhibit feature if a hazard is created by this action. Be

suretotestallcombinationsofhighand low alarm inhibit actions before
