PROGRAMMING INSTRUCTIONS

The 5700/5800 can be configured to run in Time Delay or Auto Start/Stop with lockout. Machines are factory set with Auto Start/Stop with 4 hour Lockout. A Smart Relay controls how the machine will operate by using three internal timers; these timers are adjustable. The following is a brief description of these timers:

Timer 1: ‘Lockout Timer’ (Time Delay) • Timer 1 de-energizes (lockout) the machine if

not being used for a preset time. If machine has ‘Locked out’ it can only be re-energize by pressing the ‘Pump On’ switch. Timer 1 is factory set to 4 hours.

Timer 2: ‘Auto Start/Stop Timer’ • Timer 2 allows the pump to run in bypass for a

preset time. If the pump runs in bypass longer than the allotted time the timer will drop power to the motor contactor and machine will be in standby mode. Squeezing the gun trigger will restart the pump (if Timer 1 has not locked out). Timer 2 is factory set to 30 seconds.

Timer 3: ‘Reset Delay Timer’ • Timer 3 controls how long the pump must run

before resetting the ‘Lockout Timer’ (Timer 1). This allows the pump to run long enough to re-pressurize the system if there is pressure loss when not in use. Timer 3 is factory set to 15 seconds.

To change to the parameters of the internal timers in the Smart Relay complete the following steps:

1. Turn on the power to the machine but do not press the start switch. Remove the front panel and then the control panel cover. NOTE: Use extreme CAUTION when reaching into the control box, the machine has live power. Once powered the Smart Relay window will display the following screen, see figure 1 (if screen does not appear press the left/right arrow keys or until correct screen appears).

2. Press the ESC key located next to the display win-dow and under the arrow key pad (see figure 2). Pressing the ESC key will access the Parameter Assignment Menu.

3. Using the up/down arrow key or , move the (>) cursor to ‘Set Param’ and press OK to confirm (See figure 3). The display window shows the first parameter (Timer-1), see figure 4.

NOTE: Ta is the accumulator timer and T is the adjustable timer (the variable that changes)

4. Press OK to change the value of Timer-1. Using the left/right arrow key or , move the cursor to the desired field and use the up/down arrow keys or to change this value. See figure 5.

5. Each timer has optional units of time in seconds (s), minutes (m), and hours (h). To change the unit of time use the left/right arrow keys or to move the cursor to the unit field. Change the unit of time using the arrow up/down keys or . Once all the values have been set press OK to accept. See figure 6.

6. Press arrow up/down keys or to select the next parameter to change (Timer -2). Repeat steps 4 and 5 to change the Timer-2 parameters. See figure 7.

7. Press arrow up/down keys or to select the next parameter to change (Timer -3). Repeat steps 4 and 5 to change the Timer-3 parameters. See figure 8.

8. Once all timers have been set to the desired time press ESC twice to return to the Input display screen. See figure 9.

Factory Set Parameters (Auto Start/Stop with Lockout)TIMER VALUE DESCRIPTION

Timer 1 04:00 Hours Turns machine off after 4 hours of non-use. To restart push the ‘Pump On’ switch.

Timer 2 30:00 Seconds Pump will run in bypass for 30 seconds before shutting off, machine is still in standby mode. Pulling the gun trigger will restart the pump.

Timer 3 15:00 Seconds In case of pressure loss when machine is in standby, the pump can run up to 15 seconds before resetting ‘Timer 1’ (lockout)

Time Delay ParametersTIMER VALUE DESCRIPTION

Timer 1 03:00 Minutes When machine is not in use, pump will run in bypass for 3 minutes and shut off. To restart push the ‘Pump On’ switch.

Timer 2 01:00 Hours To operate in time delay mode timer 2 must be deactivated. This is done by setting timer 2 to value greater than timer 1.

Timer 3 15:00 Seconds Pump must run more than 15 seconds to reset timer 1.

OPTIONAL — WATER INLET SOLENOID

A water inlet solenoid can be added to the machine that will open only when the machine is running or in standby. The solenoid closes when the machine is off to prevent possible water overflow when unattended.

Installation • Connect a 24V/AC normally closed solenoid on

the water inlet, contact local Hotsy dealer for solenoid options.

• Connect solenoid to the remote terminal using 16 ga minimum wire

• Wire solenoid to remote terminal according to figure below

Before powering up machine, fill float tank to prime the system.
