Setpoint
A programmable temperature that has been selected for hopper, hoses and applicators.
Setpoint Limitation
This is a universal maximum temperature for all zones (218°C [425°F]). The programmer cannot
program a temperature setpoint higher than the setpoint limitation.
(Future feature, not on V2.0)
Stepped Function
Used on systems with electric applicators only. After programming the temperature (to the softening
point of your adhesive, see your adhesive manufacturer), the controller holds all electric heads at
the operator-selected temperature for ten minutes before releasing them to operating setpoint. This
feature allows for the stabilization of the electric valves.

Error Indication Messages

A controller display of "EO1" indiates that the selected zone (ie, a hose, applicator or the hopper)
has an open sensor. A display of "EO2" indicates a shorted sensor.
If either alarm occurs, first verify that the following three connections are made correctly:
1. The ASU-to-hose connection(s) located at the back of the ASU,
2. The hose-to-applicator connection(s),
3. The RTD Input connections (X4) located on the Control Printed Circuit Board.
If the problem is not with a connection, check the sensor and replace if necessary.

Software Chip (EPROM) and Checksum

The software EPROM is on the Control Printed Circuit Board (see Ch. 7). Inscribed on the control-
ler's software chip is information that is required if your controller needs service, including the con-
troller's checksum.
