INTRODUCTION Thank you for purchasing the new SST-4 from Wired Rite Systems. This product has been designed for the highest reliability while providing your critical remote START-STOP-THROTTLE functions. The following items are included with the SST-4 shipment: SST-4 circuit board with optional enclosure or mounting base. Connector kits for wiring mating connectors to the six-pin connector and the two four-pin connectors.
OPERATIONAL FEATURES Ability to remotely operate engine controls, including Start/Stop, Throttle and E-Power. Active and Inactive modes. Active mode when Master enable signal is provided to the SST-4. Auto Stop On Loss Of Pressure Mode allows the monitoring of engine or PTO functions and automatic fail-over to preset emergency power settings. Inputs triggers include: MASTER, Start/Stop (SS), Auxiliary (AUX), Throttle (TH), Pressure Sensor (PRESSURE) .
CONNECTIONS Detailed wiring diagrams and notes are found in Appendix I. Please refer to that section for information and suggestions for your specific requirements. This manual assumes that the installation was completed using these suggestions. Figure 2 shows the SST-4 board layout, highlighting key components. Figure 3 shows the terminal connections for the wiring to the SST-4. Wiring diagrams. Wiring diagrams for common configurations of the SST-4 board are shown in Appendix I. Wiring diagrams.
INSTALLATION AND POWER-UP 1. After all of the connections have been made, and the unit has been mounted securely, the SST-4 is ready to be powered up. The following procedure describes the power up and initial checkout. 2. With the ignition switch in the ON position, turn on the “Master” switch to power up the SST-4. On initial power up the SST-4 will perform a self-diagnostic test to verify that all of the functions are operating correctly.
PROGRAMMING Table 3. Programmable parameters and settings. *Denotes Factory Setting.
Programming Procedure The following procedure describes how to view and change settings for SST-4 operation. These procedures require the user to access the pushbuttons on the SST-4 circuit board: “MENU”, “UP”, and “DOWN”. 1. Press the “MENU” button on the SST-4 board. The display will show the board’s current operating configuration, starting with “A2”, that is, the system is set for dual plunger mode. 2. Press “MENU” again, and the next parameter is displayed.
TROUBLESHOOTING If a problem is encountered, the following procedure can be used to troubleshoot the system, and identify and fix some of the more common problems. If the problem is not easily identified, please contact Wired Rite for assistance at 1-800-538-7483. Before beginning the troubleshooting, please check these five items: 1. System Lock-up. The processor on the SST-4 board can go into a locked-up situation if the power is toggled on and off at a rapid rate.
7. Apply signal to activate the Start, Stop, and E-power functions as defined in the programming settings. Verify that the 4-character display shows “St”, “SP”, and “EP” as expected. If not, check programming settings (see Programming section). Set parameter “L” to 1 and if the display is flashing “St”, “SP”, or “EP”, then there has been a fault in that circuit. Check the manual circuit breakers and reset if necessary by pressing the yellow tab on the circuit breaker. 8.
TEST MODE OPERATION: Test Mode is used to verify the wiring and operation of the system. CAUTION: when in Test Mode, the vehicle or Emergency Pump may start unexpectedly. Whenever possible, Test Mode should be used for bench testing. If used when installed, two mechanics should be present, and extra care is strongly advised. To enter Test Mode, press and hold all three buttons: “MENU”, “UP”, and “DOWN” for five seconds until all of the segments flash in the middle two 7-segment displays.
Appendix I. Wiring diagrams The SST-4 can be wired in various ways for a variety of engine control applications. This section includes wiring diagram for three common configurations: 1. Aux E-Power Battery. Emergency Power is provided from an Auxiliary Battery. Programming state would include “C4”. 2. No Aux E-Power Battery. Emergency Power is provided from normal battery (there is no Auxiliary Battery) and E-power control is from Start/Stop or Throttle signals. Programming state would include “C1” or “C2”.

Wiring Diagram 2 No Aux E-Power Battery, power supplied from main battery through waterproof circuit breaker. Emergency Power is provided from normal battery (there is no Auxiliary Battery) and E-power control is from Start/Stop or Throttle signals. Programming state would include “C1” or “C2”. EMERGENCY HYDRAULIC PUMP SOLINOID D2 STARTER D5 D6 STARTER J1 RED/WHT (J1 PIN-3) D7 START/STOP THROTTLE AIR CYLINDER AIR CYLINDER AUX.
Wiring Diagram 3 No Aux E-Power Battery, simplified. Power supplied from main battery through ignition switch circuit. Please note that this circuit puts extra demand on the ignition circuit. Wire of sufficient gauge must be used. Check your vehicle electrical specifications to be certain that his circuit will not damage the ignition system. Emergency Power is provided from normal battery (there is no Auxiliary Battery) and E-power control is from Start/Stop or Throttle signals.
Appendix II. Connection Tables 1. Ignition relay on SST-4 is “Normally Closed”. If power is not supplied to the board, the ignition circuit will be closed and the ignition function will not be interrupted. 2. The SST-4 hour meter can be triggered either by the MASTER signal or the SPARE signal on J1 Pin 1. This is user-programmable, as described in Section 5. PROGRAMMING. 3. T1 and T2 are identical, except T1 controls Relay 1 and T2 controls Relay2.
Appendix III. REPLACEABLE PARTS The following are replaceable parts on the SST-4. To order please see website at http://store.wiredrite. com/store.

Appendix V. Auto stop on loss of pressure Mode This mode will force the SST-4 into STOP mode if loss of pressure is detected on a userinstalled circuit. This will then allow the user-specified stop mode settings to control. This mode is especially useful in the situation where the vehicle stalls and the e-pump must be used to control the aerial device.
