Current Transformer
Calculating set value for heater failure
Set Value = [(Current value without f
Current value with heater failure )] / 2
eg. A 200V system with three1KW heaters
would normally draw 15 amps
[1000 / 200 ]*3 = 5A *3 = 15A
If one of the heaters is out of order, the current
draw is now 5A*2 or 10A. The Set Value must
be adjusted to (15+10) /2 or12.5A

In the RUN LIST grouping of the
OPERATOR’s section, select HEAT or
COOL for parameter ULSL.
The parameter can be adjusted
from 5 to 600 seconds. It defines the time
required to open the valve completely.To
determe this parameter correctly, close the
valve manually. Be sure the valve is fully
closed; then reopen it manually without
stopping and measure how long it took to
reopen it completely. Add 5% to this value
and enter it for this parameter.
The parameter determines the
increments as a percentage of the Ultt
parameter and can be adjusted from 0.1 to
5.0 %. If the valve oscillates while opening
or closing, INCREASE this parameter’s
value!
