Factory setting:
FAULT MESSAGE
! Note!
• It is very important to read and comply with the information on the switching
characteristics of the relay output, (see page 109).
• It is advisable to configure at least one relay output as a fault output and define the
outputs' failsafe mode.
• The relay output is configured as a normally open (NO or make) contact by default. It
can be reconfigured as a normally closed (NC or break) contact by means of a jumper
on the relay module (see Operating Instructions Proline Promass 83, BA
059D/06/en).
• If you select OFF or ON, the only function shown in the CONFIGURATION function
group is this function ASSIGN RELAY (4700).
ON VALUE
(4701)
! Note!
This function is not available unless LIMIT VALUE or FLOW DIRECTION was selected in
the ASSIGN RELAY function (4700).
Use this function to assign a value to the switch-on point (relay output pulls up). The
value can be higher or lower than the switch-off point. Positive or negative values are
permissible, depending on the measured variable in question (e.g. mass flow, totalizer
reading).
User input:
5-digit floating-point number [unit]
Factory setting:
0 [kg/h] or 2 [kg/l] or 200 [°C]
! Note!
• The appropriate unit is taken from the function UNIT VOLUME FLOW (0402) or
UNIT MASS FLOW (0400).
• Only the switch-on point is available for flow direction output (no switch-off point). If
you enter a value not equal to the zero flow (e.g. 5), the difference between the zero
flow and the value entered corresponds to half the switchover hysteresis.
