Operating instructions

0341

As the card proceeds through the cycle a missing

peg in one of the ribs closes the circuit of the

corresponding micro-switch in the programmer

and activates that particular function.

Never cut the formula without first laying it out on

the card. Mark the pegs to be eliminated and then

carefully re-check it against your formula plan.

Cutting the pegs from the card is accomplished

with a special pair of cutters, delivered with the

machine, or by using a 1/4 inch chisel. To insure

fault-less programmer operation, it is important

that the pegs be cut off cleanly and completely.

Note that the programmer stops during water fill

and heating (on heated machines). It starts

advancing again when the water level (or pre-set

temperature) has been reached.

The water inlet valves and the drain valve are

electrically interlocked and cannot open

simultaneously. This simplifies the card cutting.

For example, if hot water is required for two or

more consecutive fillings (two washes and a

rinse), the hot water rib may be cut for the entire

length of these three fillings, including drain time.

When the drain valve opens and the water level

drops, the water inlet valves will not open as they

are interlocked with the drain. The moment the

drain valve closes, the required water inlet valve

opens immediately.

The programmer motor which drives the

mechanism is activated only if a water level has

been satisfied or the drain valve is open. During

the water fill, the programmer will not advance the

formula card until sufficient water has been

admitted to satisfy the programmed water level

(low or high). The machine will achieve the proper

water level regardless of variations in water

pressure. During the drain period, the programmer

motor is energized through a separate relay to

keep the programmer advancing the card. If you

call for a buzzer signal (Rib M) when the machine

is empty of water, be sure the drain (Rib K) is cut

to energize the drain valve. The programmer will

thus continue to advance the card until it reaches

the buzzer signal or stop position.
