ALARM AND TRIGGER

Loud 95dB audio buzzer with a bright red LED and a relay trigger signals the alarm.

APPLICATIONS

AFR too rich The alarm activates when too rich mixture is detected.
AFR too lean The alarm activates when too lean mixture is detected.
A combination of AFR too rich and AFR too lean alarms can be used to tune for a specific AFR window.
EGT too high The alarm activates when EGT exceeds a safe user selected level.
RPM too high Shift-light functionality with a bonus of audio alarm and a relay trigger.
TPS too high The alarm activates when TPS exceeds a selected level.
USER1 Input too high The alarm activated if a sensor connected to the USER1 input exceeds a selected level.
USER1 Input too low The alarm activated if a sensor connected to the USER1 input is lower than a selected level.
USER2 Input too high The alarm activated if a sensor connected to the USER2 input exceeds a selected level.
USER2 Input too low The alarm activated if a sensor connected to the USER2 input is lower than a selected level.
Relay trigger Open or close a relay circuit to activate or deactivate additional devices at a set warning level. Typically used to add a control to your boost setting, nitrous or alcohol injection and other devices capable of engine destruction.

The Audio Visual Warning and Trigger Box alarm is activated by Zeitronix Zt-2 Wideband AFR Meter. The audio alarm can be deactivated by adjusting the switch SW1 inside the box. The visual alarm and a relay trigger are always active.

The ZAVT-1 blue wire connects to the Zt-2 Warning Output (white wire with a blue stripe).

SOFTWARE SETUP

Open the Zeitronix Logging Software. Connect the Zt-2 Wideband AFR Meter into a PC COM port and power up the Zt-2. Make sure the log graphs are shown on the screen. Then open the Warnings and Triggers menu by selecting "Hardware" then "Warnings:: Setup...".

Parameters can be selected for use in a Simple or a Complex Warning.
A Simple Warning will be triggered when any of selected parameters exceed preset warning level.
A Complex Warning will be triggered when all selected parameters exceed preset warning level.

In an example below a warning will be activated if the Boost exceeds 7 psi.
A warning will also be activated if the AFR mixture is leaner than 12.5 AND the RPM is greater than or equal to 6500.

Many other warning combinations can be set by using the ZDL software.

The alarms are saved in the Zt-2 flash memory and kept after disconnecting a PC laptop or disrupting power.

Zt-2s manufactured after Jan 22 2007 have additional alarm duration feature, which keeps the alarm active after the alarm condition is removed. The alarm duration can be setup between 0-240 seconds.

The Zt-2 has a single warning output wire. Simple and complex warnings both activate the ZAVT-1 using this warning output wire.

OPTIONAL RELAY CONNECTION

The Zeitronix ZAVT-1 box is capable of triggering an optional relay at a preset warning level. Connect the ZAVT-1 WHITE wire ONLY to the negative side of the relay; otherwise, leave the WHITE wire unconnected and protected from accidental connection to any other signal.
Relay wire colors correspond to relays purchased from Zeitronix.

COMPATIBILITY

ZAVT-1 is compatible with the Zt-2 Wideband AFR Meter REV 9 or higher. Zt-2s purchased after May 9 2006 are compatible and support Simple Warnings. Zt-2s purchased after September 1 2006 support both Simple and Complex Warnings. You can check the Zt-2 compatibility by accessing the warnings feature in the Zeitronix Data Logging Software Version 2.0.8 or higher. To do this open pen the Zeitronix Logging Software. Connect the Zt-2 Wideband AFR Meter into a PC COM port and power up the Zt-2. Make sure the log graphs are shown on the screen. Open the Warnings and Triggers menu (v2.0.18 or choose "warnings setup" from the "Hardware" menu in the version 3 software. The following message is displayed if an incompatible Zt-2 AFR Meter is detected.
