10.5.2.3 Backshift conditions
If a ROCOT alarm is active, two conditions must be met for the alarm to go back.
•
The current measured value must be smaller than the switch-
off value for “alarm off”
•
The calculated slope must be negative
If both conditions are fulfilled, the alarm switches off again.
10.5.3 Cyclic relay test
For each alarm, a “cyclic relay test” can be activated. This switches the relay according to the set parameters.
The cyclic switching ensures a longer service life of pumps and motors, which a normally never in operation.
This prevents a defect (sticking due to corrosion, …) on the connected pumps or motors.
10.6 Simulation
If required (commissioning, troubleshooting, …), individual functions (sensor values, relay states) can be
simulated. The simulation can be started either directly on the device (
menu -> simulation
) or via the web
interface (
home -> start simulation
). The simulation mode is active for 15 min from the last action, or can be
shut down directly by the user.
10.7 Firmware update
Firmware updates can be installed via the web browser (
system
). If the update notification is active, a
message is displayed as soon as a new firmware version is available. If the device is not connected to the
internet, the new firmware can be downloaded from the homepage
. Then the update file can
be selected under (
system -> manual installation -> select firmware
) and carried out via the button “manual
update installation”.
10.8 Alarm counter
There are separate alarm counters for each alarm. These alarm counters store the last 20 shutdowns with
cause and timestamp. If, instead of the correct time, a date around 1970 is displayed, the set date + time of
the real-time clock is not correct. For help see 11. Error search.
10.9 Temperature statistic
The temperature statistic records the residence time of the respective sensor at a certain temperature. There
are 20 predefined temperature ran
ges (10°C each, e.g. 0,0 … 9,9 °C) from 0,0 up to 199,9 °C. In addition,
there is an area for <0,0 °C and one for >200,0 °C. This statistic is available twice resettable via manual reset
(or by program change) and cumulated (reset only at program change or set of factory settings).
10.10
Program update
The preinstalled programs can also be updated if necessary. If a newer version is available, it will be
displayed in the program table. Here it is directly possible to install the revised version. You can also add new
programs via this function.
10.11
Modbus
The devices type TR640IP has a Modbus TCP interface. For more information, see the Modbus operating
manual.
