Brief Description
The slave displaying instrument (instrument) distinguishes in principle two operating
modes:
The hexadecimal display mode and pure numerical measured-value processing mode.
Note: See also section Description of Commands for Interfaces.
Note: Further information is obtained from the data sheet.
The delivery state is the hexadecimal display mode.
Hexadecimal Display Mode
Following signs can be transmitted and displayed:
Sign: +, - or none
1st position: 1 (if larger then automatically given on 2nd position)
2nd to 5th position: 0 1 2 3 4 5 6 7 8 9 A a B b C c D d E e F f - and blank character
Decimal points: ., (all positions selectable)
The output is right aligned.
Examples: Transmission Display
-1.2345 -1.2345
+1.AB.CD +1.Ab.CD
123-45 123-45
+123 +123
…±1.8.8.8.8. (Test)
-123+45 Err.2 (Error: the sign "+ " cannot be represented)
Measured-Value Processing Mode
In this mode, the instrument functions like a measuring instrument that does not fetch
measured values from an A/D converter, but via a serial interface. Several functions such as
limit monitoring are provided.
Measured values (numbers) can be processed in the following ranges: ±0.0001 to ±19999
Examples: Transmission Display
-1.2345 -1.2345
123 + 0123
…±1.8.8.8.8. (Test)
-123+45 Err.2 (Error: invalid number format)
In addition to the measured value transmission, a series of interface commands is available.
Use as Agreed
See also data sheet. The manufacturer is not liable for damages that arise from improper
or regulation alien use.

Installation
Prior to installing the instrument into the switch panel, the corresponding adhesive labels
(see section Scope of Delivery) should be adhered to the luminous fields that are on the
right hand side of the display. To do this, remove the frame from the front panel, and re-
move the front screen by grasping the lower carving.
Cut and peel off labels as needed and adhere label, e.g. "V", to rectangular luminous field
on display, "Hold" label for the control input function (see chapter Activating the Function
of Control Input) to the bottom luminous field, and "SP1" or "SP2" for the measured value
(see section Setting the Measured Value) to upper luminous field.
Note: SP2 should be adhered to the top most luminous field.
To install the instrument into the switch panel, the panel shall be cutout according to the
drawing on data sheet. Remove the screws from the instrument and slide the instrument
into the cutout. Then reattach the screws and fasten the instrument with the screws to
the switch panel. Screwdriver can be used to tighten screw clips.
Note: Screw clamp assignment for the connections, e.g. power supply, is obtained from
the data sheet.
Attention: When connecting the supply voltage, the operating data given on the type
label, which is located on upper side of instrument, should be taken into account.
Getting Started
Settings are not necessary to get started, however, if the presetting is insufficient, the in-
strument has to be adapted to the applications.
After switching on or applying the supply voltage, the instrument runs a self-test; should
errors be detected, they are shown on the display. The error number and supplementary
number appear in succession. After 10 seconds, a self-test is repeated.
Explanation and Correction of Errors
Error Report
Error codes have the following meaning:
Err.0 EPROM defective or not correctly readable
Err.1 EEPROM defective or check sum is incorrect
Err.2 Incorrect or faulty transmission data
C.Err Incorrect input of codes for the safety level
(see section Setting the Safety Level)
Manual PM984
State July 2002 - All subject to change without notice 5

Error Correction
If Err.0 or Err.1 are displayed, the instrument should be taken out of service and sent to
the manufacturer.
If Err.2 is displayed, the data and transmission parameters or interface operating mode
(see section Description of Commands for Interfaces, item Operating Mode) should be
checked.
Recall delivery state
In Service Mode (see section "Determine the Safety Level") the delivery state can be
loaded by entering Code +3210 and saved by selecting SaVe.
Handling
1. Remove small cap on front screen and or compete front screen to gain access to the
turn/press switch (switch) to perform settings.
2. Use a small insulated screwdriver to carry out settings.
3. Press the switch with the screwdriver to invoke the first menu; turn the switch to run
through the menus (see section Menu Structure).
4. Push to activate currently displayed menu and the first menu item will appear.
5. Turn or press the switch once again to carry out the settings in the individual menu
items.
6. The display flashes, and can be changed by turning.
7. Numeric settings such as limit values are carried out dynamically, i.e. the quicker the turn-
ing the larger the numeric steps.
8. The number input is accepted when the switch is pressed again, thereafter the previouse
activated menu reppears.
9. The settings are stored permanently only after the SAVE menu is invoked and the
switch is pressed.
10.If the switch is not actuated within 10 seconds, the menu and the instrument restarts
with a reset if necessary and the old values.
Attention: If the instrument is opened, conducting parts that lie on the electrical po-
tential of the measuring input will be exposed and can be touched.
If the settings are carried out with non-insulated screwdriver, the conducting parts that
lie on the electrical potential of the measuring input can be touched.
Menu Structure
The instrument has several operating modes that are activated with corresponding codes.
Only those menu items are displayed that are enabled for the set safety level.
Note: The delivery state is the service mode.

Setting the Limit Values - SP1 / SP2
In this menu, the corresponding limit values (break over points) can be set. When the toler-
ance range monitoring is activated, corresponding limit value pairs are made available, dur-
ing which the upper and lower limit values are assigned automatically (see section Setting
the Relay Functions rEL.1 / rEL.2).
Note: The menu SP1 / SP2 is displayed only if the functions, limit high and limit low,
were set in advance in the menu Func at rEL.1 or rEL.2 and the protected mode is
not activated. To represent the switch point of the limit value on the display, the corre-
sponding label should be adhered to corresponding luminous field as described in sec-
tion Installation.
Setting the Hysteresis of Limit Values - Hy.1 / Hy.2
In this menu, the default value of the switching hysteresis for the corresponding limit value
or limit value pairs can be set. Only positive values are possible. For a failure-free limit
monitoring, the value shall never be greater than the measuring range or half of the toler-
ance range (see Setting the Relay Function -- rEL.1 / rEL.2)
Note: The menu Hy.1 / Hy.2 is displayed only if the functions, limit high and limit low,
were set in advance in the menu Func at reL.1 or reL.2 and the protected mode is
not activated.
