CAUTlON
High Voltage and High Temperature can cause injury and are a
Fire Hazard. Please read all instructions, have only skilled profes-
sionals wire the unit, and use an approved temperature and/or
pressure safety control. Even the best components can be
damaged or may not failsafe.
Warning Notes:
1. "B" Output for resistance load only.
2. An open thermocouple will disable the INDEX function.
3.
Note also that in units utilizing only heating output the cooling gain
should be set by user to the equivalent heating gain. The inverse
IS
also true.
4. A unique algorithm in the Model 6075 prevents continual buildup of
oscillation due to grossly misadjusted rate/reset (-rt-) or gain. When
this occurs the unit will control at some point higher or lower than set
point outside the proportional band. If this occurs -rt- was probably set
too low and/or gain set too high.
5.
-rt- sets Rate (Derivative) and Reset (Integral) action. The number dis-
played is the Rate time in seconds. This is tracked by the Reset time in
seconds (1:6 ratio).
