Chamber
Enhancer with SPLIT BAND SMART™ Staging
used exclusively for
Micristar
controller cycle times of 1.5 to 2.2 seconds
(relays
not included)
The
Typical time delay approach to staging deprives chamber of sufficient
controllable power output for certain operating conditions, but
the new A2192 Chamber Enhancer utilizes the SPLIT BAND SMART™
Staging approach which provides 100% controllable power output for
all operating conditions by providing a smooth linear transition
from 0 to 100% Hi output power for each controller output cycle.
Other key features include:
- Simplifies
setup of chambers with multiple stages of heating/cooling
- Hi Heat
& Hi Cool power ratio enable action.
Hi Heat/Cool are enabled based on the ratio
(%) the Lo Heat/Cool contributes to the total output.
- Smooth
linear transition of Hi output. Provides a smooth linear transition from the
Lo to Hi output stages.
- Eliminates
discontinuity seen in time delay staging.
There are no uncontrollable power transitions
of the Hi Cool or Heat when the controller demand transitions
from less than 100% to 100% output demand.
- MTO (compressor
time-out).
Fixed at 3 minutes
- Two MTO
Actions Provided.
PROM -CMTO (standard) or specify -CHMTO
(optional)
-CMTO:
The MTO is started whenever a cool signal (TB1-3) is received. Ext. de-humidify
MTO is started whenever a signal is received on TB3-2, TB3-3
logic output, TB3-4 +5vdc.
-CHMTO:
The MTO is started whenever a cool (TB1-3) or de-humidify signal is received.
Ext. de-humidify is disabled.
- Selectable
bypass for Lo or Hi Cool.
Lo/Hi Cool Bypass Select Jumper - On for Lo
Cool, Off for Hi Cool
Bypass
output is automatically disabled when the MTO times out.
- Eight socketed
locations.
AC or DC plug-in solid state relays (SSR)
for control and staging outputs
- Independent
second channel input/outputs on TB3.
- Snap track
mounted, with optional SSRs.
- Mounting
dimensions 3" x 12".
- Upgrade
existing A2192 boards with a simple MIS027 PROM change.
