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

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<
