Level
O P . L O OUTPUT LOW
Adjust to limit the maximum cooling
power applied to the process or to
apply a minimum heating power +100.0%
0.0 (heat
only)
-100
(cool) L3
D . B A N D CHANNEL 2 DEAD BAND
Period when no output is demanded
from either channel 1 or channel 2
Adjust, for example, to increase the
period when no heating or cooling
power is applied Off or 0.1 to 100.0% of the cooling proportional
band
OFF L3

HEATING HYSTERESIS 1 to 9999 display units 1 L3 On/off
only
H Y S T . C COOLING HYSTERESIS 1
S A F E SAFE OUTPUT POWER
To set the output level in a sensor break
(open circuit) condition -100.0 to 100.0% limited by OP.HI and OP.LO 0.0% L3
F . M O D FORCED MANUAL OUTPUT MODE
Selects how the loop behaves on
transfer from Auto to Manual.
Transfer from Manual to Auto is always
bumpless. none Transfer between Auto/Manual/Auto is
bumpless none L3
SteP Transfer from Auto to Manual, the
output goes to a pre-set value (F.OP)
Last Transfer from Auto to Manual, the
output goes to the previously set
manual value
C o o l . t NON-LINEAR COOLING TYPE
This selects an algorithm most suited to
the type of cooling. Typically used in
extruders. Lin Linear Conf
OIL Oil cooling
H20 Water cooling
Fan Forced air cooling
F . O P
FORCED OUTPUT
To pre-set a value for the Manual output
when F.MOD = STEP -100.0 to 100.0% limited by OP.HI and OP.LO 0.0 L3

Auto To select automatic operation L3
Man To select manual operation
OFF Control outputs inhibited
l b r LOOP BREAK STATUS No Shows the current status of loop break. Read
only
YES
T U . H I TUNE HIGH LIMIT. Set this to limit the
maximum heating output during
autotune Range between OP.HI and OP.LO
+100.0 L3
T U . L O TUNE LOW LIMIT. Set this to limit the
maximum cooling output during
autotune
