Operating Instructions
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.
IMP Series 15 and 30 Amp
Temperature Controllers
IMP/P Series 10 and 15 Amp
Temperature Controllers
1.1 General Description
The IMP and IMP/P Series are
microprocessor-based PID controllers
specifically designed to perform most
operator functions automatically. The IMP
Series are plug-in units, while the IMP/P
Series are portable, standalone instruments. Both are self-adjusting and capable
of maintaining a very high degree of
temperature accuracy over a wide range
of operating conditions.
CAUTION
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.
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 that will automatically interrupt the
controller output power when any thermocouple (T/C) fault is detected, when operating in closed-loop mode. In open-loop
operation, the display shows percentage
of power as set by the power control
potentiometer (0-100%).
1.3 Operation
Note: Any flashing display indicates that
the controller has detected a fault. Refer
to section on Faults.

1.2 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.

Position Mode select switch to
closed-loop (“O”).
Set temperature on Setpoint switch.
Turn on AC power.
After a short reset delay, the
measured temperature will be
displayed. If the temperature is 30°F
(17°C) or more below setpoint, the
under temperature alarm display
(lower segment of the leftmost digit)
will flash. If the temperature is 30°F
(17°C) or more above setpoint, the
over temperature 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”).
Power to load indicator (the decimal
point of the leftmost digit) will be
on if any power is being applied to
the load.
When any of the T/C faults are
detected, output power will be cut off
automatically and the temperature
display will be blanked out. The
leftmost digit will show “ ” for (T/C
open), “ ” for (T/C reverse) or
“ ” for No Heat and flash twice
per second.
1.
Position the mode select switch
to open-loop (“ ”).
2.
Turn the AC power on.
3.
After reset delay, the controller
will display the percentage of
output power as adjusted by the
power control knob. The
percentage power indicator will
be on. Thus 0.00 corresponds to
0% (no power) and 1.00 corresponds to 100% (full power).
The leftmost digit will display
open-loop mode (“ ”).
75% power is shown as 0.75.
Automatic Operation with
CompuStep ® System
Manual Control Pre-Set
When starting from cold, it is recommended that the CompuStep system be used to
lengthen heater life considerably.
The following procedure can be used to
pre-set the Manual Power Control Knob
position in the event of a thermocouple
break in closed-loop operation.
1.
2.
3.
4.
Position the mode select switch to
CompuStep mode (“ ”).
Set the desired temperature on the
setpoint switch.
Turn on the AC power.
After reset delay, the measured
temperature will be displayed. If
temperature is less than 200°F
(93°C) the controller will enter the
CompuStep mode. This is indicated
by the step symbol “ ” on the leftmost digit. During this mode, the
controller gradually increases power
to load in small steps. After 5
minutes or when the temperature
reaches 256°F (124°C), the
controller will exit from CompuStep
mode and automatically go to
setpoint. Any thermocouple faults
detected during the 5-minute interval
will cause the CompuStep mode to
end prematurely. When CompuStep
ends, the controller will operate as
described in the Automatic
Closed-Loop Operation section. If
temperature is above 200°F (93°C),
controller will bypass CompuStep
and go directly to setpoint.
A good thermocouple is required to start
with, as this procedure compares the
temperature attained using automatic
(closed-loop) control with that obtained
using manual (open-loop) control.
When the temperature is the same using
either automatic or manual control, then
the position of the Manual Power Control
Knob is correct.
Procedure for Manual
Control Pre-Set
7
a.
Adjust controller for closed-loop
operation and obtain good molded
parts. This will adjust the controller to
the proper temperature.
b.
Position the module select switch
to open-loop and set the manual
control knob to roughly 25%. Wait for
10 seconds, than momentarily switch
to closed-loop mode to examine the
temperature. If it is above the set
point, the manual power is too high to
maintain proper temperature. If it is
below setpoint, the manual power is
too low. Adjust the power control
knob accordingly, wait for 10

60-second interval during start-up. It
takes 60 seconds to detect “No heat”
when power is first turned on in
closed-loop mode.
seconds, then re-examine the
temperature by switching mom
entarily to closed-loop mode. Repeat
this procedure until the temperature
is the same in either automatic or
manual control.
If CompuStep is active, the test is not
performed until after CompuStep is
finished (5 minutes). When “No heat”
alarm is detected, output power is cut off.
Faults
1.

3.
Over temperature alarm:
A constant over temperature alarm is
most likely caused by a shorted triac
in the controller or incorrect or
shorted mold wiring. Switch module
power off as quickly as possible and
replace controller or correct wiring
error. Check for thermocouple or
heater cross wiring.
What to do:
Under temperature alarm:
Under temperature alarm is normal
during system start-up before the
setpoint is reached. If under
temperature persists, a No heat
fault will occur.
Try resetting the controller by
turning its AC power OFF and then
ON.
b.
If “No Heat” persists, then the problem
could be one of the following.
1) Open heater or load.
2) Thermocouple shorted. Switch to
manual mode to override this
condition.
3) Load circuit open. This can be
caused by an open power cable,
an open connector or a failed triac
in the controller. Exchange the
module with a known good module
to eliminate suspect triac or module.
Thermocouple open or reversed:
If any T/C fault is detected during
closed-loop operation, the output
power will be cut off. If it is necessary
to apply power to the load during a
T/C fault condition, the controller can
be switched to manual mode. The
output power will be a function of the
manual control knob setting. Since
the controller is now operating in
open-loop mode, extreme care must
be taken when adjusting to prevent
excess output power that would
overheat the load.
4.
a.
4) Slow heater. Use higher power
heater or operate in manual mode
until setpoint is achieved.
5) Thermocouple too far away
from heat source that causes less
than 2°F (1°C) rise in 60 seconds
due to thermal lag. Move thermocouple as close to heater as
possible or use heater with built
in thermocouple.
No heat:
6) To defeat “No Heat” circuit, if not
used or required, remove jumper
J4 and that circuit will no longer
be active.
The IMP series controller has
included in its microprocessor a
program that detects that the
temperature is not rising as it should
in response to full power output. “No
heat” is defined as the condition
under which the temperature does
not increase more than 2°F during a

User’s Selected
Jumper Option
1.
Do not enable SafeChange unless
the mainframe supports this feature.
For degree Celsius operation, install
shunt on PC board marked J1
(marked C on newer models)
2.
For 120 Vac input operation, install
the 2 jumpers on the PC board as
shown.
3.
For 240 Vac input operation,
install the 1 jumper on the PC
board as shown.
Checking Mainframe for
SafeChange Capability
To check the mainframe for
SafeChange capability:
a. Turn off power to the mainframe.
b. Remove a blanking panel or a
controller that is OFF, so you can
look into the mainframe.
c. Look at the lower connector block
on the backplane.
1) If a metal clip is in the third
position from the top in the
connector block, then the
mainframe supports
SafeChange. SafeChange
should be enabled on the
controller before installing it in
the mainframe to reduce the
possibility of damage to
the controller.
Note: If units are factory wired for 240 Vac,
remove 240 V jumper prior to installing a
120 V jumper.
SafeChange Hot Swap Feature
™
Controllers are shipped with SafeChange
disabled, because the controller will not
work if the SafeChange feature is enabled,
but the mainframe does not support
SafeChange. You can enable SafeChange
quickly and easily using a jumper as
described in this section.
Use of the SafeChange feature does
not eliminate the need for careful
installation and removal of controllers.
Always turn off power to the controller
and the mainframe when installing or
removing a controller.
Basic set up choices are made using DIP
switches as described in this section. The
switches in a Series IMP Hot Runner
controller are set at the factory for J thermocouple as the input type, with Fahrenheit as
the unit of measure for North America, and
Celsius for other shipping destinations.

2) If the third position in the
connector block does not
contain a metal clip, then the
mainframe does not support
SafeChange. You can add a
clip to convert the mainframe.
2.
Enabling the SafeChange Feature
Controllers are shipped with
SafeChange disabled, because
the controller will not work if the
SafeChange feature is enabled,
but the mainframe does not
support SafeChange.
You can enable SafeChange quickly
and easily.
To enable the SafeChange
feature, remove the jumper
block from JP6.
Location of Clip in Mainframe
to Support SafeChange
If you don’t see JP6, the controller
in hand may pre-date the
SafeChange feature. In addition to
JP6 in the location shown above,
controllers that support SafeChange
also have one edge connector
shorter than the others. If all the
edge connectors are the same
length, the controller does not
support the SafeChange feature.
3.
Adding a SafeChange Clip to
the Mainframe
You can convert an older mainframe
to support SafeChange. To make
the conversion, you must add a clip
to the third position in the lower
connector block (on the backplane)
in every slot; see the illustration.
The clip is p/n 216D001U01.
Location of SafeChange
Jumper JP6
To install the clip:
a. Turn off power to the mainframe.
b. Remove the back cover of the
mainframe.
c. Position the clip in the third
(open) position in the lower
connector block, and press
The clip will snap into position.
