Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama
tion point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
Overview
System Description
The heated platen kit is a field installed kit to add heat to
the platen. The additional heat may change the viscosity
properties of the material and allow the material to flow
easier through the system.
Power Requirements
A 25A (minimum) - 30A (maximum) circuit breaker must
be installed on the incoming power supply.
* Add to power requirements of ExactaBlend AGP
Advanced Glazing Proportioner system. Amps maxi
mum per leg shown.
** 190-264 voltage range acceptable.
WARNINGWARNINGWARNING
WARNING
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can cause electric
shock.
• Turn off and disconnect power at main switch before disconnecting any cables and before servicing
or installing equipment.
• Connect only to grounded power source.
• All electrical wiring must be done by a qualified electrician and comply with all local codes and
regulations.
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe
burns:
• Do not touch hot fluid or equipment.

Installation
Grounding
Ground the system as instructed within this manual.
1. Access the Platen
a. Perform Change Drums procedure in the
Air-Powered Ram manual. Do not load a new
drum.
b. Perform Shutdown procedure in the Exacta
Blend AGP Advanced Glazing Proportioner,
Setup-Operation manual.
c. Thoroughly clean all material that may be found
on the top of the platen.
d. Turn off all sources of power to the machine.
To avoid serious injury or machine damage, all
electrical connections need to be done by a qualified
electrician in compliance with local codes.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.

electrical enclosure.

Maintenance
332511B 15
Maintenance
Platen Maintenance
If the platen does not come out of the pail easily when
the pump is being raised, the air assist tube or check
valve may be plugged. A plugged valve prevents air
from reaching the underside of the plate to assist in rais
ing it from the pail.
1. Turn off main disconnect at the machine.
2. Allow equipment to cool.
3. Relieve pressure and disassemble air assist valve.
Refer to Supply Systems Repair-Parts manual.
4. Clear air assist tube in platen. Clean all parts of
valve and reassemble. Refer to Supply Systems
Repair-Parts manual.
5. Remove bleed stick from platen. Push bleed stick
through bleed relieve port (P) to remove material
residue. See FIG. 3.
6. Remove platen covers. See FIG. 3.
a. Remove platen cover fasteners (F).
b. Remove both platen covers (C) and ground wire
from platen.
7. Remove any excess fluid. Use a soft wire brush on
heater coils (H). See FIG. 3.
8. Inspect platen heater blocks (B) or heater (H) for
burn or melt spots. Replace platen heater if neces
sary. See FIG. 3.
9. Check for loose connections and damaged wires.
10. Follow steps in reverse order to reassemble platen.
NOTE: Torque platen cover fasteners (F) to 60 +/- 10
in-lbs (6.8 +/- 1.1 N•m) for 55 gallon platen.

Troubleshooting
Before performing any troubleshooting procedure:
1. Perform Pressure Relief Procedure In the Exacta
Blend AGP Advanced Glazing Proportioner,
Setup-Operation manual.
2. Turn off main disconnect at the machine.
3. Allow equipment to cool.
Try the recommended solutions in the order given for
each problem, to avoid unnecessary repairs. Also,
determine that all circuit breakers, switches, and con
trols are properly set and wiring is correct before assum
ing there is a problem.
Common Problems
Problem Cause Verification Solution
Heating is slow. Low power. Measure voltage across cir
cuit breakers. Voltage
should measure between
190 and 264 Vac.
1. If voltage is lower than
expected, use electrical
schematic to locate
faulty wiring or connec
tion.
2. Have a qualified electri
cian service electrical
components.
Heating over shoots. Defective solid state relay. Verify for given zone that
temperature does not
increase when zone is dis
abled.
Verify RTD wire or heater
power cord is attached to
correct heat module.
Replace relay.

Troubleshooting
332511B 17
No heat. Tripped circuit breaker. Visually check circuit
breaker for a tripped condi
tion.
Determine cause of tripped
circuit breaker. Then repair
fault and reset main circuit
breaker.
Low power. Measure voltage across cir
cuit breakers. Voltage
should measure between
190 and 264 Vac.
1. If voltage is lower than
expected, use electrical
schematic to locate
faulty wiring or connec
tion.
2. Have a qualified electri
cian service electrical
components.
Cable unplugged/loose
wire.
Check for loose or discon
nected wires and plugs.
Attach plug/wire.
Incorrect temperature set
point.
Verify zone has a correct
temperature setting on the
controller.
Enter Setup and enter cor
rect temperature.
Contactor not closing. Turn on heat for zone A1
and ensure contactor
closes.
1. Verify that there are no
other error conditions
that would prevent
heater from starting.
2. Replace contactor.
