expanded to include a complete range of
panel, rack-mounted, and open-card process
controllers, highly efficient SCR power con­trollers and solid-state motor contactors, and
specialized temperature control products and
systems for the plastics industry.

Athena’s products are sold and serviced
worldwide through a network of authorized
sales representatives and distributors.

OPERATING INSTRUCTIONS

IMPSeries 15 and 30 Amp Temperature Controllers
PIMSeries 10 and 15 Amp Temperature Controllers

Section I. General Description

The IMP and PIM Series are microprocessor based PID controllers
specifically designed to perform most operator functions
automatically. The IMP Series are plug-in units, while the PIM
Series are portable, stand-alone instruments. Both are
self-adjusting and capable of maintaining a very high degree of
temperature accuracy over a wide range of operating conditions.
A digital display eliminates parallax error caused by conventional
analog methods of display. This enhances the accuracy of the
controller while making information easier to see.

Simplified controls and the use of status symbols allow the
operator to make adjustments easily. The status display also
provides visual indication of normal or abnormal operating
conditions in both controller and load.

All that is required of the operator is to set the temperature
desired. From that point on, the controller will automatically
perform all the operations required to achieve and maintain the
selected temperature.

Included in the design is a built-in safety feature which when
operating in closed-loop mode will automatically cut off the
controller output power when any TC fault is detected. In open­loop operation, the display shows percentage of power as set by
the power control potentiometer (0-100%).

The IMP plug-in controller is capable of receiving a standby
command from the SAM auxiliary module. When a standby or low
heat command is acknowledged from the SAM during closed­loop operation, the controller will operate with a fixed setpoint.
When receiving a standby command during open-loop operation,
the output power of the controller will be reduced to 1/4 of the
front panel power control setting.

The IMP controller also sends alarm status conditions to
the SAM auxiliary module for annunciation and remote
control functions.

Section II. Installation (IMP Series Only)

All IMP Series controllers are ready to use as shipped from the
factory. Prior to installation into a mainframe, make sure the
voltage, Hz and degree options are as ordered and correspond to
the Product ID label.

Never insert or remove a controller from a mainframe
with the AC power on. Hazardous potentials exist on
components inside the mainframe and controller.
Always disconnect AC power to the mainframe when
servicing.

CAUTION

6

To install a plug-in controller into a mainframe, release the
locking device on the lower edge of the unit by pulling the plunger
gently away from the panel. Align the upper and lower edges of
the printed circuit board on the controller with the mainframe
card guide slot and slide in until the rear connector is completely
engaged. Lock the controller into the frame by depressing the
plunger on the locking device.

Section III. Operation

Note: Any flashing display indicates that a fault has been detected
by the controller. Refer to section on

A.Automatic Closed-loop Operation

1- Position Mode select switch to closed-loop (“o”).
2- Set temperature on Setpoint switch.
3- Turn on AC power.
4- After a short reset delay, the measured temperature will

be displayed. If the temperature is 30 degrees F (17°C) or
more below setpoint, the undertemperature alarm
display (lower segment of the leftmost digit) will flash. If
the temperature is 30 degrees F (17°C) or more above
setpoint, the overtemperature alarm display (upper
segment of the leftmost digit) will flash. During alarm
conditions, temperature display will also flash. If the
temperature is within alarm limits, the display will stop
flashing, and the leftmost digit will display closed-loop
mode (“o”).

5- Power to load indicator (the decimal point of the

leftmost digit) will be on if any power is being
applied to the load.

Faults.
