4.1 Operator Intervention

When a formula starts, the machine processes the goods automatically during normal operation.
However, it can be necessary for the operator to intervene to:
• add a chemical
• correct an error
• make a manual change to a wash formula, or cancel the formula
In most cases, the operator signal will sound when it is time for the operator to intervene.
4.1.1 Chemical Supplies Intervention
BNCLJT06.C03 0000214535 A.10 C.3 C.2 9/11/20 11:21 AM Released
The operator should receive instruction from the chemical supplier for the type of chemical sys-
tem provided. This can be:
Pumped chemical system a system that injects liquid chemicals into the machine when called
for by the formula. The only intervention normally required is to ensure that the chemical
containers that supply the chemicals to the system remain at a safe level.
Optional 5-compartment supply injector a system in which the operator places a measured
amount of chemical in each compartment before the start of each wash cycle. Each compart-
ment is dedicated to a type of chemical (detergent, bleach, sour, softener, etc.). When the for-
mula calls for a given chemical, the compartment for that chemical is injected with water to
flush the chemical into the machine.
Although not common, it can be necessary to manually add a chemical that is not provided by the
pumped chemical system, or to reload a supply injector compartment with a different chemical
while a formula is in progress. In this case, the formula can be programmed to turn on the opera-
tor signal when operator intervention is required.
When the machine desires a chemical injection, the step timer pauses, the operator signal sounds,
and a dialog box ( shown in Figure 13 ) appears on the controller.
