Example out of diagram A:
• Adjusting the voltage source for an output of 7.6 V!
The instrument calculates this value from the rise angle of the two
predecided end points (in example A: 7.6 V correspond to an external
setpoint temperature of 152.0
°C ).
After returning the VFD display to standard display, this value is
displayed in line 2 (Example: SP 152.00
°C).
Notice:
If this adjustment is not correctly performed at two different points, the setpoint setting
will be incorrect.
Important:
The usable temperature range between > LVAL < and > UVAL < is limited to the
configured working temperature range of the circulator resp. of the unit combination
(working temperature range see technical specifications)
9.9.3.
ALARM-output / Stand-by-input
ALARM
Alarm output (10)
(for external alarm signal)
Possible parameters:
(STANDBY or ALARM or AL-STBY)
This socket is a potential-free change-over contact. With the adjustments
in the menu item > AL-OUT Function< all operating conditions can be
signaled without having to change the pin assignments.
Signification of the terms under menu item >Function< :
The circulator is in condition >STANDBY< or >ALARM< or >AL-STBY< -
both conditions are signaled.
Alarm-TYPE
Possible parameters:
( NORMAL or INVERS )
For >TYPE- NORMAL< pins 2 and 3 are connected in any case
according to the selected > AL-OUT Function<
For >TYPE- INVERS < pins 2 and 1 are connected in any case according
to the selected > AL-OUT Function<
