GRAPHIC READOUT
The Graphic Readout is a 160 X 80 Pixel Monochrome LCD Display. In Normal operation mode the Readout shows measured
Temperature Value, Set Temperature Value, Alarm / Process Status, Elapsed Soak Time (if enabled & running) & Date/Time.
Other process information like Mapping Channels PVs / Alarm Status, Process Status & Stored Records can be viewed using
screen scroll feature.
In Set-up Mode, the Readout displays parameter names and values that can be edited using front keys.
KEYS
There are six tactile keys provided on the front panel for configuring the controller and setting-up the parameter values.
The Table 1.1 below lists each key (identified by the front panel symbol) and the associated function.

BASIC OPERATIONS
Section 2
Upon power-up the controller display shows screen depicted in Figure 2.1(a) for 2 Seconds. The controller runs through a self-
test sequence for checking its Real Time Clock, SD Memory Card, internal Communication Link and Parameter Storage
Memory (EEPROM). The and symbols indicate whether a check is passed or failed, respectively. In case any one or
more checks fail, the controller starts executing its normal operation but ‘Self Checking’ screen is halted until front panel
“Acknowledge” key is pressed. This is followed by screen depicted in Figure 2.1(b) for next 2 Seconds. This screen shows the
controller model name, Hardware Version and Firmware Version.
RUN MODE
After the Power-up display sequence the controller enters into RUN Mode. This is the normal operation mode wherein the
controller starts PV measurements, Alarm monitoring and Control Loop execution. The Display comprises of several screens
described below. The screens appear one-after-the-other upon pressing (Scroll) Key while in RUN Mode.

The PPI “Multi-Purpuse Temperature Controller” provides control outputs for driving, both, heating & cooling sources. The
user can enable any one or both outputs depending upon the test equipment type and application. If both outputs are enabled
(by setting the parameter ‘Control Strategy’ to Heat + Cool) and if the cooling source is compressor then the controller offers
various strategies for switching the compressor as described below.
Compressor Switching Strategies
1. Compressor Off
The compressor is kept Off. This strategy is usually selected for temperature values significantly above the ambient
temperature.
2. Compressor On
The compressor is kept On regardless of the measured or set temperature value. This strategy is usually selected for
temperature values significantly below the ambient temperature.
3. SP Based Strategy
In this strategy, the chamber temperature range is split in two zones by setting the parameter 'Boundary Set-point' (BSP).
Refer Figure 5.2.

OFF
The zone at and above the boundary SP ( ) is referred as Heat Pre-dominant zone and that below the boundary SP ( )
is referred as Cool Pre-dominant zone. The controller automatically switches between the two zones depending upon the
Temperature SP. If the Temperature SP is below boundary SP, Cool Pre-dominant zone is active and the compressor is kept
ON. If the Temperature SP is at or above boundary SP, Heat Pre-dominant zone is active and the compressor is kept OFF. This
strategy eliminates the need for the user to manually switch the compressor ON or OFF.
If the parameter Control Zones is set to “Dual”; separate tuning can be performed in the Cool and Heat Pre-dominant zones for
accurate control in each zone. The controller maintains separate sets of Proportional Band, Integral Time & Derivative Time
constants for each zone that are automatically selected and used by the controller depending upon the active zone.
However, if the parameter Control Zones is set to “Single”; the controller uses a single set of Proportional Band, Integral Time
& Derivative Time constants for both zones.
