If when turning on,
the display will first
go to segment check
Digital controller is
constantly beeping.
No heat on either on
left, right, upper, or

functioning.
Beeper is not
functioning.
One of the three
heater platens not
close to set point.
2. Control needs to reset.
Sensor in one of two zones lost its
continuity. Depress TEMP. While
depressing TEMP depress either up
or down arrow to locate error
message PROB (zone 1, lower
platen, zone 2 left upper platen, zone
3, right upper platen.) If occurred
when depressing the up arrow
indicates either the left or right
platen has the open sensor or
Probe.
Sensor lost it's continuity as shown
on a muti-meter.
The mechanical relay on the switched
side is not opening to regulate
temperature. Hold TEMP button
then depress either the down or up
arrow (zone 1, lower platen, zone 2,
left upper platen and zone 3, right
upper platen.) RLY will display on
problem zone indicating the damage.
If the mechanical relay(s) on the coil
side are receiving 12vdc indicates the
controller is functioning properly. If
there is no voltage on the switching
side of the relay to the heaters, the
relay is not working properly.
Beeper has failed.
The offset function in the controller's
setting needs to be adjusted to

ohm RTD sensor to underside of
the platen and reconnect to
controller. Upper left and right
sensor for replacement on upper
platens, lower platen sensor for
replacement for lower platen.
Disconnect prob that is open (no
continuity as shown on a multi-
meter. Must replace sensor
