Page 4 DESCRIPTION DPS3000 Series instrum ents are m ulti-channel s canners th at pack a number of functions in to one unit. Tasks that require mu ltiple monitors can n ow be accom plished by usin g only a single un it.
Page 5 DISPLAYING PARAMETERS DPS3000 Series k eeps track of v arious paramet ers and these m ay be dis play ed by push ing appropriate k eys on the fron t panel.
Page 6 setpoint, dif ference betw een any two selected chann els or just run as a tim er. In the timer m ode the unit keeps track of process run time with crystal controlled accuracy . Elapsed Time display format is 'HH.MM.SS' for hour s, minutes, a nd seco nd s.
Page 7 Display tim e for each chann el is programm able from 1- 999 seconds (16.65 m in.). This is usef ul for adjusting dis play tim e to a rate w hich is con sistent with the type of process being m onitored. Scan time for each channel is independent of display tim e.
Page 8 a) The first one is a mom entary display in w hich the deviation is indicated for a short tim e. Fo llo win g this brief display tim e, the unit reverts to its normal m ode o f op eratio n (scannin g, differential, timer etc.). To achieve this, f irst select th e channel w hose setpoin t deviation is des ired.
Page 9 Once the correct pass -code has been entered, th e display s hows 'SYS CH' , w ith 'CH' blinki ng. At this p oint t he ope rato r may choose b etween making channe l settings ( C H ) , or system settings (SY S ) . Use ^v key to togg le between CH and SYS m odes.
Page 10 CHANNEL CONFIGURATION After en tering correct pass-code and s electing the blinkin g 'CH' (ref. SETUP section), the display show s 'SLCt CH' (for "Select Channel"). Use ^v key to display the desired channel. Selected chan nel will be displayed in the form at 'CHANEL x' (wh ere x=channel #).

Page 12 SETPOINT value. Once the desired SETPOINT value is displayed, push SETUP key to enter that value and go on to setup ch annel 1's operational m ode. Setup for Unive rsal Relay (Channel 1 Relay) Chann el 1 relay can be conf igured to work as a universal relay or as Channel 1 relay only .
Page 13 Setup For Engineering Units After settin g a channel's relay for NORMALLY OPEN/CLOSED operation, the nex t parameter to be set are the 3 letters that follow the pr o cess value in th e display. These 3 letters represent the measurem ent units for that particular chan nel.
Page 14 Example #2: Use of the LOW SCALE Param eter Setup f or a 4-20ma tran sducer si gnal correspondin g to 500-2000 degrees F ahrenheit tem perature i.e. 500 degrees at 4ma and 2000 degrees at 20m a (one degree res o lution): DECIMA L POINT = 9999 HIGH SCAL E = 2000 LOW SCA LE = 500 OFFSET = 4.
Page 15 Setup For Relay Latch/Non-Latch After settin g DISP LAY TIME, the next parameter determ ines wheth er the output relays w ill operate in a Latched or Non- Latch ed mode. Relay Latched Mode: In this m ode the relay is activ ated when its L IMIT value is exceeded an d stays activated until the operator m anually resets the relay.
Page 16 desired va lue is display ed, push SETUP key to enter that value and go to the nex t step. Voltage Range Setup (for millivolt inputs) For Millivolt input units, the display f irst shows 'HV rnGE ' (for " Hi gh V olta ge Range " ).
Page 17 PEAKS A very useful fun ction of DPS3000 is tracking th e highest (peak ) and the low est (valley ) point attained by each ch annel. This is particularly helpful if an ope ratio n is not being constantly w atched or is left u nattended (e.g. overnig ht).

UNDER NO CONDITION SHOULD THE RELAYS AND OPEN COLLECTOR OUTPUTS BE OPERAT ED BEY OND THEIR RATED CAPACIT Y. DOING SO CAN DAMAGE THE UNIT PER MANENTLY. The status of the relay s for all the ch annels is indicated on th e front panel by a row of LEDs.
