ACTUAL STATUS
RELAY
MODBUS register:
Relay output 1
Relay output 2
Data type:
Access:
4740
3813
4013
Integer
read
Use this function to check the current status of the relay output.
A jumper on the contact side defines the relay output as a normally open (NO or
make) or normally closed (NC or break) contact (see Operating Instructions
BA107D).
Display:
0 = BREAK CONTACT OPEN
1 = BREAK CONTACT CLOSED
2 = MAKE CONTACT OPEN
3 = MAKE CONTACT CLOSED
SIMULATION
SWITCH POINT
MODBUS register:
Relay output 1
Relay output 2
Data type:
Access:
4741
3814
4014
Integer
read/write
Use this function to activate simulation of the relay output.
Options:
0 = OFF
1 = ON
Factory setting: OFF
! Note!
• The “SIMULATION RELAY” message indicates that simulation is active.
• The measuring device continues to measure while simulation is in progress, i.e.
the current measured values are output correctly via the other outputs.
• If the “BATCH VALVE 1” option was selected in the ASSIGN RELAY (4700)
function, the functional test takes place by means of the BATCH PROCEDURE
function (7260), see Page 146.
" Caution!
The setting is not saved in the event of a power failure.

! Note!
The function is not visible unless the function SIMULATION SWITCH POINT
(4741) is active.
Use this function to define the status of the relay output during the simulation.
This value is used to test downstream devices and the measuring device itself.
Depending on the relay configuration (as make or break contact) the following
selections are available.
Options:Relay output configured as normally open (make) contact:
0 = BREAK CONTACT OPEN
1 = BREAK CONTACT CLOSED
Options:Relay output configured as normally closed (break) contact:
2 = MAKE CONTACT OPEN
3 = MAKE CONTACT CLOSED
