Description

The Series 5000 is designed as a fully programmable digital
temperature indicator and miniature datalogger. The displays
are 0.56" in-line red LED type. The menu driven display
prompts and 14-segment alphanumeric characters make
programming simple. Front panel programming is
accomplished through three front panel keys. Degrees F or
degrees C are indicated by a green, .4" seven segment LED
located to the right of the main display. Resolution is
selectable either 1° or 0.1°. A single dash (-) displayed at the
left of the readout indicates a negative temperature. Positive
readings are inferred (no dash displayed). Overload is
indicated by an 'OL' on the display. Plus OL (+OL) indicates
a positive over range condition or an open thermocouple.
Negative (-OL) indicates a negative over range condition.
The 5000 is powered by a 100-240Volt, 50-400Hz AC source
and uses a switching power supply for maximum input power
flexibility.

The unit will accept, depending upon the model, J,
K, E, T, R and S thermocouples or 3/4-wire 100 ohm
Platinum RTD’s, either .00385 or .00392.

Serial communications is standard RS232. This bi­directional serial port allows the user complete program set­up, programming and operational capability. All controls and
features are selectable through the front panel. The front
panel lens may be removed to install or remove the program
lockout jumper or adjust the analog output if necessary.
Power and serial connections to the meter are made to the

1

rear of the instrument via a removable Euro-style terminal
block. Sensor connections are made by screw terminals also
on the rear of the instrument.

Minimum and Maximum values are always available
for viewing. On the Basic model (no options), the information
is accessible through the front panel menu system.
Configuration settings are stored in on-board memory and are
not affected by power loss.
The following models are available (see list below).

PGM

Operation

Your indicator is programmed by a series of menu driven
displays that are operated by three front panel pushbuttons;
Program-PGM, Arrow-∆, and Enter-ENT.

ENT

PROGRAM ARROW ENTER

Addressing the main menu items configures the indicator.
The indicator has a program lockout jumper located behind
the front panel lens. Removing the jumper will prevent any
front panel changes of the indicator programming. The
indicator may still be programmed via the computer interface.
When using the Series 5000 Viewer Software the front panel
keyboard is automatically disabled. The basic unit has three
main menu items that define the configuration of the
indicator and one calibration menu.

1. INPT: Sets up sensor type, °F/°C, and

1 deg/0.1 degree resolution.

2. MATH: Selection enables viewing of either

minimum or maximum value.

3. CAL: Used for calibration

.

12

The following menu items are displayed only when the
appropriate option is installed-

5. ALM1/ALM2: Sets relay trip points to a

programmed value as well as other alarm

related parameters

6. AOUT: Programs the indicator to translate the

display to a proportional analog output signal

7. MULT: Configures indicator for multiple same

type input sensors

Pressing the PGM key allows you to access any of the menus
listed above by placing the indicator in program mode,
indicated by a ‘P’ lit to the right of the display. Placing the
indicator in PGM mode will prevent the indicator from
performing measurements. Any alarm monitoring will be
disabled.

If the PGM key is pressed anywhere within a menu,
the menu reverts to the previous menu level. Repeatedly
pressing the PGM key will return the indicator to the display
mode. Choices within a menu are viewed by pressing the
ARROW key. A menu item is selected by pressing the ENT
key for selection, or edited by pressing the ARROW key.
Generally, the ARROW key allows you to scroll horizontally
through a selection of choices while the ENT key enables you
to make selections and move down vertically to the next menu
item.

If the alarm option is installed and the alarm relays

13

are set to unlatch manually (‘MAN'), relay #1 may be
unlatched by pressing and holding the ARROW key while
pressing the PGM key. Pressing and holding the ARROW
key while pressing ENT key will unlatch relay #2.

Note: Basic units shipped from the factory are configured
for type K thermocouple, °°F, 0.1 degree resolution.

Multiple Input models are shipped from the factory with a
5 second scan rate, channel 1 on, all alarms off with the
setpoint set LOW at 0000.

Dual Alarm/Analog Output models are shipped with both
alarms off, set for LOW and 0000. Deviation value set to

0000. Analog out is set to scale from 0°° to 1000° ° with
either 0-10VDC or 4-20Ma out.

Sensor Setup

Example: To select Type K thermocouple, °F, and 0.1°

resolution...

STEP 1. Press the PGM button. PGM will appear on the

display. The °F/°C LED will change to P (for ‘Program
Mode).

STEP 2. Press the Arrow key until INPT appears on the

display. Open the Input Menu for programming by pressing
the ENT key. One of the seven thermocouple types and two
RTD types will appear on the display (J,K,E,T,R,S,392,385).

14

Scroll through the various sensor types by pressing the Arrow
key until a “K” appears on the display. Press the ENT key to
select K type thermocouple.

STEP 3. An F or C will appear. Pressing the Arrow key

repeatedly will cause C and F to alternate on the display.
With F on the display, select degrees F by pressing the ENT
key. DCPT will appear. The Arrow key allows you to toggle
back and forth between 0.1 and 1.0 degree resolutions.

STEP 4. To select 0.1° resolution, with 0.1 on the display

press the ENT key. At this point the display will show the
MATH menu item*. To open the MATH menu for
programming, press the ENT key. To go back to the mode,
press PGM key. In order to scroll through the various menu
items press the Arrow key.

*MATH functions are available on units with Multi-

channel option installed only through the Doric
5000 Viewer Software.

Math Function Setup

Example: View the maximum temperature value recorded.

Note: A running record is kept of the minimum, and
maximum values of temperature. Nothing is
required to initiate this recording. These values are

15

there whenever you need them. You can display the
Minimum or Maximum value by following the steps
below.

STEP 1. With the MATH menu on the display, open this

menu item by pressing the ENT key. MIN is on the display.

STEP 2. Press the Arrow key to toggle between MIN and

MAX. When the display shows MAX, press the ENT key and
the display will now indicate the maximum value. The
MIN/MAX memory may be reset at this point by pressing the
Arrow key. With CLR (CLEAR) on the display, press ENT.
His will restart the recording process. To go back to the
current temperature display, press the PGM button and the
display will indicate the current temperature reading.

Multiple Input

The multiple input option will enable the user to
monitor up to 6 same type thermocouple inputs, or 3 three­wire/four-wire RTDs. Any number of channels can be
selected manually or scanned automatically. Alarm limits
may be assigned to individual channels. One NO/NC 5 amp
115VAC relay contact is available for high or low alarm limit
programming.

Two modes are selectable for the multiple input
option- manual (MAN), and automatic (AUTO). MAN mode
allows the user to view a selected channel. Pressing the arrow
key advances the display to the next active channel. The
channel number is indicated by a .4” green LED located in
the upper left-hand corner of the display. To begin scanning,

16

select AUTO. The scan rate is selectable in one-second
increments between 5 and 20 seconds. The display readout
will then sequentially show the temperature of the active
channels. Any number of channels may be selected for
scanning.

If an alarm limit is exceeded on any displayed
channel, the display will flash, and the relay contact will
latch. The relay will remain latched until the alarm condition
clears. In scanning mode the display will flash on the alarm
channel as it scans.

By using the Doric Series 5000 Viewer, the Series
5000 can log and send multiple channel data through the
serial port making it a miniature datalogger.

Dual Alarm

The alarm card has two 5 amp/115VAC relays for high, low
or deviation setpoints. The alarm card is available by itself or
with analog output (either voltage or current). Relay setpoints
are programmed through the front panel menu or via the
serial port. An alarm limit may be disabled within the alarm
menu by selecting OFF at the first menu prompt. If OFF is
selected the display will return to the next main menu item
for further programming. If ON is selected the menu proceeds
down through the alarm menu for further setpoint
programming.

The relays can be operated in MAN or AUTO mode.
In AUTO mode, the relay unlatches by itself once the alarm
limit is no longer exceeded.

In MAN mode the relay is reset manually. However,
the display continues to flash until the alarm limit is no
longer exceeded.

17

- Pressing and holding the Arrow key and pressing

the PGM key resets Relay 1 (ALM1).

- Pressing and holding the Arrow key and pressing

the ENT key resets Relay 2 (ALM2)

Note: When the Viewer Software is being used, the
front panel keys are disabled. Relays must therefore
be reset using the Unlatch buttons on the Viewer
control panel.

When HIGH is selected, a temperature greater than
or equal to the limit value will cause an alarm. When LOW is
selected, a temperature less than or equal to the limit value
will cause an alarm.

Using Deviation

Deviation allows the user to assign alarm limits above and
below the normal operating points of a process. If the
temperature remains within the high and low deviation
setpoints no alarm occurs. If the temperature equals or
exceeds either the high or low deviation limits an alarm
occurs. Hysteresis and delay are also programmable for
deviation setpoints (see following explanations). Deviation
allows the user to assign two setpoints per alarm relay for a
total of four alarm setpoints per alarm option (See drawing
below). This could be useful for indicating a warning
condition with one relay and an emergency condition for the
other relay.

18

Hysteresis

temp

Hysteresis or deadband is used to delay the unlatching of a
tripped relay. Hysteresis may be selected within the alarm
menu as either ON or OFF. Hysteresis is selectable from 0-99
degrees in 1° increments. For example, a limit with a
hysteresis value of 5 assigned to it means that the display
value must return 5° below the alarm setpoint before the
alarm condition is cleared (the relay resets). Hysteresis
assumes negative values for HIGH limits and positive values
for LOW limits.

Delay

Programming the meter for alarm delay prevents an alarm
trip for a specified period of time (0-9 seconds). An alarm
delay would be used whenever an unstable or noisy input
signal is present. By filtering out short duration alarm
conditions, alarm delay prevents unnecessary alarms from
occurring.

19

Analog Output

The analog output option translates the indicators’ display
reading to a proportional analog output signal. There are two
versions of the analog output option, either 0-10VDC or 4­20ma. Both voltage and current outputs are scaleable within
their ranges and are similarly programmed. Note that the
analog output is active only in the display mode. As soon as
the indicator is put in the program mode, indicated by a P in
the lower right hand corner of the display, the output goes to
its zero output value. The display reading can be scaled from

-999 to +9999, which enables the user to use only a portion of
the full scale if necessary.

Analog Output Setup

Example1: Program the indicator to output 4.0 ma at 32.0°

F and 20.0 ma at 500° F...

STEP 1. Press the PGM button. PGM will appear on the

display. The °F/°C LED will change to P (for ‘Program
Mode).

STEP 2. Press the Arrow key until ALOG appears on the

display. Open the ALOG Menu for programming by pressing
the ENT key.

STEP 3. A LOW or HIGH will appear. Pressing the Arrow

key repeatedly will cause LOW and HIGH to alternate on the
display. With LOW on the display, select LOW by pressing
the ENT key. The digits 0000 will appear with the left most

only monitor the selected channel. The selected

channel and its’ ID is displayed under the

simulated display

- The next active channel may be viewed by

pressing the NEXT button located beneath and

to the left of the simulated display

- If a selected channel alarms and the next

channel is selected, the flashing red indicator

turns yellow. This indicates that this channel

was in an alarm condition when last viewed.

Logging data

To create a file of logged data, open the preference menu by
clicking the Preferences button located in the upper right
hand corner of the Viewer window. Open the LOG menu by
clicking the LOG button. You may name your file any
acceptable Windows 95 name. The default file extension is
.dat. The path for your log file will be shown on the main
control panel window. Select the interval (between 0-24
hours at 1 minute increments.) at which logs will be taken.
