Page 1The Safe Guard 64 is an advance safety device aimed to simplify control, and to warn theoperator should a safety parameter be breached.It utilises the latest digital micro-controller technology to ensure reliability and performance.These instructions are intended for use by an authorised installer.Modifications, manipulation or improper repairs can affect the operability and safety.overviewconnectionThere are two connection options shown in the wiring diagrams on page 1 and 2. In thetypical connection, Output 4 Common should be connected to ground, if the accessoryrequires negative switching.The Alternative Connection shows the wiring required if the accessory running throughOutput 4 requires positive switching.
Page 4installation guideMount the Safe Guard 64 in a dry safe, secure place away from heat and humidity.If possible, select an inconspicuous area that will not be routinely accessed.Make sure the device is kept clear of moving parts or debris.Also ensure the device is safe from moisture or liquids.Please ensure you read this complete manual as fitting instructions and testingprocedures are incorporated throughout.
Page 5General Input 1 and 2 are momentary inputs. Depending on the DIP switch setting,by briefly connecting the input to Battery Positive or Battery Negative, it will toggle onand off General Output 1 and 2 respectively.If General Input DIP switch is enabled (ON), releasing the Park brake will switch OFFGeneral Output 1 and 2.The Door Switch and Park Brake switches are set to low active (by default, Switch toGround) but can be configured either way. If the Door Switch is active (open door)while park brake is NOT active (OFF), the on board buzzer will immediately sound for5 seconds before alarm (Output 4) is activated. Applying the Park Brake will disableBOTH buzzer and alarm immediately. Once the door is opened, the alarms latch onunless the Park Brake is applied. It is good practice to apply the park brake BEFOREopening the door.operation overview
Page 6operation overview continuedIf the Daytime Running Light function is set to be controlled by Battery Voltagesensing, Day Time Running Light (Output 3) is turned ON with a delay of 5 secondsonce the engine is running and the Alternator is charging. If either the Head Light orPark Light is turned ON the DRL’s are turned OFF immediately. The DRL’s are alsoturned off with a delay of 20 seconds once the battery voltage falls below the pre setthreshold setting.If the Daytime Running Light is set to be controlled by the Ignition Switch, DaytimeRunning Light (Output 3) is turned ON with a delay of 5 seconds once the IgnitionSwitch is turned ON. If the Head Light is turned ON the DRL are turned OFFimmediately. The DRL is turned OFF with a delay of 20 seconds once the IgnitionSwitch is turned OFF.If any of the DIP switches are changed, a power reset (remove power for 5 secondsand re-connect) must be performed for the changes to take effect.Note: Disconnect Battery before doing any connection.Note: Use this image as a template for further diagrams in this manual.5A5A10A10A15ABottom ViewTop View
