The logic turns on output Q44 for the left chamber using event 1 while event
2 becomes the center chamber. Output Q40 becomes the right chamber
control output using event 7 with output Q35 being enabled for the max heat
output control. Outputs Q32 and Q33 for basket left and right are enabled
through events 5 and 6.
Inputs I6 and I7 are used for basket position monitoring for left and right
chamber positions respectively. The door switch input (I42) is monitored to
disable the transfer if any door is opened.
TSB Logic Enabled: Enables the logic for basket position and dual zone control. Loop 1 is set for
the left (hot) bath control and loop 2 for the right (cold) bath control. The
door switch input (I42) is monitored to disable the transfer if the lid/door is
opened. Inputs I44 and I45 are enabled for the cold bath temperature and
hot/cold pump pressure safeties respectively. If the baths are equipped with
low level floats, I46 is used as a low level warning input.
Depending on the transfer mechanism used, different inputs and outputs are
used to transfer the basket to each position. For motor operated transfer
mechanisms, outputs Q32 and Q33 for basket left and right are used to
position the basket. For air cylinder operated transfer mechanisms, outputs
Q32 and Q33 are used for the left and right movement with outputs Q46 and
Q47 used to control the up and down movement.
Events 5 (hot) and 6 (cold) with event 7 for the unload position are used to
select the three positions. Inputs I6 and I7 are used to monitor the left (hot)
and right (cold) positions. Inputs I30 and I31 are used for up and down
position monitoring for air cylinder control. On units with a motor operated
mechanism, I31 is used for the unload position indication.
Air/Motor Transfer: For DTS/VTS/TSB chambers, this sets the type of transfer mechanism used
to move the basket between zones. This setting must match the transfer
mechanism type or the transfer mechanism may be damaged.
Door Switch On/Off: Sets whether or not the opening and closing of the chamber door (when
equipped with a door switch on input (I42) turns the chamber off and on. If
enabled, when the door is opened, the chamber will shut down. When the
door is closed, the chamber will turn back on.
Door Alarm On/Off:
Sets whether or not the opening and closing of the chamber door (when
equipped with a door switch on input (I42), sounds the audible alarm and
displays an alarm message on the alarm monitor screen. This is typically
used when the door switch control is also enabled in order to alert the user
that the door is open (which is why the chamber isn’t running).
The alarm message and audible alarm will only activate when the chamber is
running and the door is opened. If the chamber events are off, meaning the
chamber is off, the alarm will not sound to eliminate nuisance alarms and
allow normal loading/unloading of the chamber when not in operation.
