Parameter Descriptions
All Options Off: Used for all standard temperature/humidity/altitude chambers.
RC Logic Enabled: Enables the logic for the RC blower motor. The logic ties event 8 to output
Q44 to turn the RC blower motor on and off with the event. Note that this
option is typically only used for retrofitting RC chambers that require event
control for the blower.
LC Logic Enabled: Enables the logic for pump control and fluid system monitoring. The logic
turns on output Q44 for the pump with event 1 and enables the input alarm
logic for high temperature (I44), pressure (I45) and flow (I46) monitoring.
VTS Logic Enabled: Enables the logic for basket position and dual zone control. Loop 1 is set for
hot chamber control and loop 2 for cold chamber control. The logic turns on
output Q44 for the hot chamber using event 1 while event 2 becomes the
cold chamber. Outputs Q46 and Q47 for basket up and down are enabled
through events 5 and 6.
Inputs I30 and I31 are used for basket position monitoring for hot and cold
chamber positions respectively. The door switch input (I42) is monitored to
disable the transfer if either door is opened.
DTS Logic Enabled:
Enables the logic for basket position and three zone control. Loop 1 is set for
the left (hot) chamber control, loop 2 for the center (cold) chamber control
and loop 3 is for the right (hot) chamber control. Loops 4 and 5 are set for
product control for the left and right basket respectively.
