12 Group RELAY OUTPUT 1/2 Device Functions Proline t-mass 65
44 Endress+Hauser
OFF-VALUE Use this function to assign a value to the switch-off point (relay output drops out). The
value can be greater or less than the switch-on point. Negative values are only permitted
for the measured variable TEMPERATURE.
! Note!
This function is not available unless LIMIT VALUE was selected in the ASSIGN RELAY
function.
User input:
5-digit floating-point number [unit]
Factory setting:
0 [kg/h; lb/h] or 0 [Nm
3
/h; Sm
3
/h] or +100 [°C]/+212 [°F]
(country dependent, → Page 71 ff.)
! Note!
• The appropriate unit is taken from the function group SYSTEM UNITS (see Page 9).
TIME CONSTANT Use this function to enter a time constant defining how the measuring signal reacts to
severely fluctuating measured variables, either very quickly (enter a low time constant) or
with damping (enter a high time constant). Damping acts on the measuring signal before
the switch status changes. The purpose of damping, therefore, is to prevent the relay out-
put changing state continuously in response to fluctuations in flow.
User input:
fixed-point number: 0.0 to 100.0 s
Factory setting:
0.0 s
ACTUAL STATUS RELAY Use this function to check the current status of the relay output.
A jumper on the contact side defines the relay output as normally open (NO or make) or
normally closed (NC or break) contact (please refer to the Operating Instructions Proline
t-mass 65, BA111D/06/en).
Display:
BREAK CONTACT OPEN
BREAK CONTACT CLOSED
MAKE CONTACT OPEN
MAKE CONTACT CLOSED
SIMULATION
SWITCH POINT
Use this function to activate simulation of the relay output.
Options:
OFF
ON
Factory setting:
OFF
! Note!
• The “SIMULATION RELAY” message indicates that simulation is active.
• The flowmeter continues to measure while simulation is in progress, i.e. the current
measured values are output correctly via the other outputs.
" Caution!
The setting is not saved if the power supply fails.
