Test Relay (
tSt
):
At this menu item it can be programmed, that a relay switches after a time don, e.g. 1 week (= 168 hours)
for the time doF, e.g. 0.2 h (12 minutes) into alarm state, for starting a pump or a fan for a short time to
make them move and thus to ensure, that bearings are not damaged by long lasting times without activity.
Select alarm with
▲/▼. Set ► switches on to
don
and
doF
.
don
= --- = test not active.
Leave menu item with button Set
► when
E
is in display.
At programs
Pr2
and
Pr3
(from firmware -01:
Pr2
,
Pr3
and
Pr6
) a test is programmed for
relay 1 (168h/0,2h).
Sensor Simulation (
Si
):
At this menu item a sensor can be selected and with the buttons
▲/▼ a measured temperature can be
simulated. All functions of the device act as if the temperature was measured in real.
15 minutes after the last button has been pushed, the device automatically returns to normal measuring
mode.
Code (
Cod
):
After setting all parameters they can be protected by activating the code lock.
After pushing Set
►, the display indicates
Pin
. Adjust with buttons
▲/▼ Pin 504 (factory setting).
After pushing Set
►, code lock can be activated or switched off.
After pushing Set
► again, an individual Pin can be selected (write down).
When code lock is activated all parameters can be seen but not be changed anymore.
In case of problems with the code lock (forgotten Pin) the lock can be switched off and the Pin can be set
back to 504, by pushing button Set
► while connecting the device to supply-voltage until
Code / oF
is
indicated in the display.
Hints
:
With programs
Pr1
to
Pr4
(from firmware -01:
Pr1
to
Pr6
) the most important parameters can be
pre-set for various applications. After that only slight changes should be necessary, e.g. setting of the
limits for the alarms.
After a menu-item has been finished, it is automatically switched to the next menu-item. E.g. after
programming the combination of sensor and alarm for sensor 1 it is switched to sensor 2 when Set
►
is pushed.
When the right decimal-point in the 7 segment-display is alight, you have left the display-mode and
you can select the different menu-items with
▲/▼ (left vertical column in flow chart).
When the right decimal-point in the 7 segment-display is flashes, you are i a menu-item. Parameters
can be changes with
▲/▼ in this mode (right side of flow chart).
Longer pushing of
▲ or ▼ accelerates the changes in the display.
Button
▲ and ▼ pushed at the same time sets actual programmed parameter to zero.
With a reset (push Set/Reset
► for 2 s) you return to display-mode from any position in the
programming-mode (last programmed parameter is stored).
