signal that is received from the laundry machine. The following list outlines the
setup of this feature: The 8
table in the electrical installation section of Laundry Master Instruction Manual). A
trigger source that can be programmed at the laundry machine will be required. The
timing of this trigger source is what determines which formula is selected by the IQ-
80. To determine the amount of signal time for any formula simply calculate as
follows:
Multiply the formula number by 2 then subtract 1
i.
6. Connect the EDSM (See EDSM instruction manuals for more details) and STU modules to the IQ-
85 by using the RJ45 patch cords that are supplied with the Laundry Master. The STU is required
in all installations, but the EDSM is optional. It is possible to connect the EDSM to the STU RJ45
jack instead of connecting to the IQ-85, providing that the STU is connected to the IQ-85. See the
following note concerning the EDSM.
EDSM Note: The EDSM module is a hand held, remote control that gives the operator the ability
to select formulas, defeat a bleach operation, or do an emergency stop. It is not necessary to use it,
but without the EDSM the only way to manually select a formula would be to select it at the IQ-85
board in the front of the enclosure.
Note: The patch cord is a communication link between the IQ-85 board, the STU and the EDSM
and can be subjected to electrical interference when not installed properly. When securing the
RJ45 patch cord between the On-Premise Laundry Controller and the Laundry Master, avoid sharp
edges, electrical motors and relays; additionally do not run parallel to electrical power lines and
conduit.

(7 X 2 = 14 then 14-1 = 13). A 13 second trigger signal to STU
input number 8 (purple and purple striped wires) will change the
Atlas to formula 7.
