Southeast Softwash
Smart Blend Commander Application Manual
Introduction: The purpose of this document is to provide an overview of the Commander remote control radio system purpose-built for use with Southeast Softwash pressure washing equipment.
Terminology: Wireless-Pair: A wireless pair is a set of devices that are wirelessly bound to one-another in a manner that persists regardless of whether or not they are powered on. Wireless-Link: A wireless link is a state of wireless connection between wirelessly-paired devices that are powered on.
Equipment: This radio system consists of a machine-controller (MC) and a hand- held unit (HH). The MC is a machine-integrated electrical/electronic device whose primary purpose is to operate machine functions based on control signals it receives from a wirelessly-linked HH. The MC also provides feedback to the HH regarding the operational status of both the radio system and the machine being controlled by its MC. The HH is a human-operated electronic device, featuring multiple operator input-controls, whose primary purpose is to send control signals to a wirelessly-linked MC. The HH also features status indicators that are used to keep the operator informed with regard to the operational status of both the radio system and the machine being controlled by its MC.

Machine-Controller – Wired-1/0:

The MC features 23 electrical/electronic connections, only 6 of which are used. These 6 connections are identified and described in the table below.

Position Description

Typical Connections & Other Notes

1

DC Ground Wire to the low side of a DC power source.

2

DC Power Wire to the high side of a DC power source through a 5 Amp

standard-response fuse. The supplied voltage must be between

11.0VDC and 28.0VDC. A switched line is recommended in order to

preserve battery life during prolonged machine off-times.

4

E-Stop Low When the MC is e-stopped (not initialized), this output is open

(connected to nothing). When the MC is initialized (not e-stopped),

this output is connected to DC Power.

5

E-Stop High When the MC is e-stopped (not initialized), this output is connected

to DC Power. When the MC is initialized (not e-stopped), this output

is open (connected to nothing).

22

SH Valve When the MC is initialized (not e-stopped), this DC voltage output

varies between 0.OV and 10.0V in 7 equidistant steps (0 and 1

through 6) according to control signals the MC receives from the HH

related to its SH input-controls. When the MC is e-stopped (not

initialized), this DC voltage output is 0.OV.

23

SOAP Valve When the MC is initialized (not e-stopped), this DC voltage output

varies between 0.OV and 10.0V in 4 equidistant steps (0 and 1

through 3) according to control signals the MC receives from the HH

related to its SOAP input-controls. When the MC is e-stopped (not

initialized), this DC voltage output is 0.OV.

Table 1: Machine-Controller Electrical/Electronic Connections

Inside the MC, an orange plug is mated to an orange connector that is mounted on the MC’s main circuit board. With the MC oriented horizontally so that the circuit board is below the orange connector, its position 1 is at the far left and its position 23 is at the far right.

Machine-Controller – Status Indicators:

The MC features 2 groups of status indicators. The first group of indicators provide information regarding the radio system’s general operational status. These indicators are identified and described in the table below.

Position Name

Typical Behavior & Other Notes

1

Power When the MC is supplied with DC power, this indicator is solid green.

Note that when the power being supplied to the MC is above 4.0V but

below the 11.OV minimum required for the MC to operate properly, this

indicator will still be solid green.

2

Fault

When the MC has experienced a detectable fault and requires service,

this indicator is solid red.

3

Program After power is first applied to the MC and it is ready for wireless- pairing,

this indicator is solid red. At all other times, this indicator is off.

4

Set

This indicator is not used for this application.

5

Link

When the HH and MC are wirelessly-linked, this indicator is typically

solid green if (1) it is receiving operator input-control information from

the HH or (2) during the 5-second activation of the HH’s status

indicators. However, if the wireless-link between the MC and HH is

experiencing connectivity issues, this indicator will flash green and if

this wireless-link drops altogether, this indicator will turn off.

When the HH and MC are wirelessly-linked but the HH’s operator input-

controls are not being used, this indicator will flash green once every 60

seconds.

When the HH and MC are not wirelessly linked, this indicator is off.

Table 2: Machine-Controller General Status Indicators

The second group of indicators provide information regarding the MC’s wired 1/0. These indicators

are identified and described in the table below.

Table 5: Hand-Held Link/Batt Status Indications

The second status indicator is a 6-position flow-rate bar. During normal use, when a HH button is pressed and when the HH is showing its status indicators for 5 seconds, the flow-rate bar indicates, by flashing red for SH and green for SOAP, the setting of their associated valve. If a valve is off, the color indicator associated with it remains off.

Radio Behavior: The behavior of the wireless-link between the HH and MC is governed by a set of operating principles that are designed to maintain a balance between HH battery life and radio system responsiveness while ensuring that the system’s top priority is operator and machine safety.

Note: The following information applies only to a HH and a MC that are already wirelessly-paired. For more information on wireless-pairing — when it’s necessary and how to do it – please see the Wireless-Pairing section of this document.

The operating principles that govern how and when a wireless-link between a HH and MC becomes active are as follows: 1 When the HH is powered on but the MC does not have power, the HH’s Link/Batt indicator will show solid yellow for 3 seconds and then the HH will power down automatically. 2 When the MC has power and the HH is powered on but the range between the HH andMC is too great, the HH’s Link/Batt indicator will show solid yellow for 3 seconds and then the HH will power down automatically. 3 When the MC has power, the HH is powered on, and the range between the HH and MC is sufficient, the MC will initialize which disengages e-stop. At this point, the system is ready for normal use.
Wireless-Pairing:
Before a HH can operate a MC’s machine-outputs, the HH and MC must be wirelessly-linked and this is only possible after the HH and MC have been wirelessly-paired. Typically, this only needs to be done once so it is done at the factory. However, in some circumstances – such as when a HH or MC has been repaired or replaced – it is necessary to wirelessly-pair a HH to a MC.
Note: During wireless-pairing, a distance of at least 3 feet must be maintained between the HH and MC to ensure proper pairing.
To wirelessly-pair a HH to a MC, use the following procedure: 1 Remove power from the MC. 2 On the HH, press and hold the button containing the star () character. 3 On the HH, press and release the ON/OFF button. 4 On the HH, release the button containing the star () character. On the HH, the Link/Batt indicator will show solid yellow. 5. Within 4 seconds, re-apply power to the MC. While the units are pairing, the HH’s Link/Batt indicator will show solid green. This can take up to 5 seconds. When pairing is complete, the Link/Batt indicator will turn off and the HH will power down.
