a)  The first one is a momentary display in which the deviation is indicated for a short time.  Following this brief 

display time, the unit reverts  to its normal mode of operation (scanning, differential, timer etc.).  To achieve this, first 
select the channel whose setpoint deviation is desired. This is done by 
pushing the 

CH. SEL

 key.  Next, push the 

RATE

  key twice.  The first push 

displays the rate/minute value.  The second push will display the deviation 
value.  Before showing the deviation,  the display will read 

'CH2 - SP'

 ( for 

CH

annel 

 

S

et

P

oint).  

 
 

b)  The second method of displaying deviation is by selecting the 

'dSP  dEN'

 option when programming  the Display Option during the SYS 

Setup.  If this method is selected, the display will scan through all the active 
channels and display their deviation.  The display format is

 'd2  1234'

 (d 

stands for deviation).  
 
The unit can also be put on HOLD at any channel by pushing the

 SCN/HLD

 key.  If any other channel's deviation is 

desired, it may be obtained by pushing the 

CH. SEL

  key.  If an attempt is made to hold the display on a channel that has 

been turned off, then the unit indicates this by displaying

 'CHx  OFF'

 (x=channel #). DPS3000 Series will keep track of 

all other parameters while programmed for this mode (i.e. limits, peaks, rate, process value, channel differential etc).  All 
of these may be displayed by pushing the respective keys. 
 

Difference Mode 

 
In this mode the system continuously displays the difference of process 
variable between any two selected channels. The two active channels are 
selected during SYS Setup mode. To remind the operator of the current 
display mode and also the two channels, the display flashes the channel 
numbers every few seconds (e.g. 

'CH1 - CH2'

 for displaying difference 

between channel #1 and channel #2). 
 
If the unit is not programmed for difference mode, the differential between 
any two of the seven channels can be briefly displayed by pressing the 

DIFF

 

key. 
 
The procedure for doing so is to first select the channel whose differential with another channel is desired. This is done by 
pushing 

CH SEL

 key. Each push on this key will display the selected channel in the format

 'CHANEL x'

(x=channel #). 

When the desired channel has been selected, press the 

DIFF

 key three times.  The first push will display the rate of 

process change on that channel. The second push will show the process deviation from the programmed setpoint. The third 
push will flash a display of the form 

'CH1 - CH2'

 and then a differential value.  Additional pushes on 

DIFF

 key will 

sequence thru the channels and will be indicated as below: 
CH1 - CH3,  CH1 - CH4,  CH1 - CH5,  CH1 - CH6,  CH1 - CH7,  CH1 - SP 
 

SETUP 

 
Setup mode provides a means to customize the monitor to suit a particular application. It allows programming such 
parameters as temperature units, limits, display mode, relay deadband, etc. 
 
SETUP mode has 2 sections: 
 

a) SYS setup section to set system parameters 

 

b) CH setup section to set Channel parameters for each channel. 

 
To get into SETUP mode, push the 

SETUP

  key twice.  The first push displays 

elapsed time and the second push  brings the unit into the SETUP mode.  
SETUP mode is indicated by 

 'SETUP'

 in the display window  (the SETUP 

LED indicator will also be illuminated) followed by 

 'ENtR  PC'

 (for 

ENt

e

P

ass

C

ode).  The passcode feature has been provided to keep unauthorized 

personnel from changing any parameters. Each of the five keys on the front 
panel are labeled with a number in the lower right corner.  The pass-code is a 
four digit combination of these numbers. Enter the pass-code when the displays reads 

'ENTR PC'

 . 

Passcode for 

DPS3000 Series  is 3254.
