The MSD 3-Stage Delay Timer is an add on module for the Power Grid ignition controller. This module
allows for three additional RPM/Time Switch outputs similar to the RPM/Time switch function built
into the Power Grid (Brown/White wire).
INSTALLATION
The 3-Stage Delay Timer module should be securely mounted near the MSD CAN-Hub. Plug the
3-Stage Delay Timer CAN connector to an available port on the MSD CAN-Bus Hub, PN 7740. Do
NOT cut the CAN-Bus connector wires.
The output wires will switch to ground any time the 3-Stage Delay Timer is programmed to activate
by Time/RPM/ or both settings. The output circuit is a low current circuit designed to be used with a
relay or activation switch. The output wires should not be connected directly to solenoids or lights
(Figure 1).

Recieves 12V switched from Power
Grid Controller. Also communicates
between modules and Power Grid
System Controller. This connector
is only used with modules added
onto the system.
These wires switch to a low current
ground when activated. Should be
used in conjunction with a relay.

OPERATION
To program the 3-Stage Delay Timer module start MSD View and connect to the 7760 with the ignition
on.
• Turn on ignition power
• Connect 7730 to PC via USB
• Start MSD View
• In the Connect box select 7760
• Click “Connect”
MSD View will display three tabs 1, 2, 3. Each tab corresponds to each output wire.
OUTPUT SWITCH 1, 2, 3:
RPM Switch: There are two settings for this function Enabled/ Disabled. Default value is Disabled. To
activate the RPM ON/OFF function change the value to Enabled.
RPM ON/RPM OFF: These settings can range from 0-15000RPM.
If the RPM ON setting is
set below the RPM OFF
setting, the RPM Switch
functions as a window
switch, and will activate
the output wire when
RPM increases above
the RPM ON setting.
The output wire will
deactivate once the RPM
increases above the OFF
setting (Figure 2).

Figure 3
If the RPM ON settings is programmed with a value higher than the RPM OFF setting, the RPM switch
functions as a hysteresis switch. The RPM switch will remain off until RPM increases above the ON
setting. The RPM Switch will remain active until the RPM decreases below the RPM OFF setting
(Figure 3).
Time Switch: There are two settings for this function Enabled/ Disabled. Default value is Disabled. To
activate the Time function change the value to Enabled
Activation Point: The setting can range from 0.00-30.00sec. This setting determines when the output
wire will activate after the launch wire is released from 12v. If this setting is set at 0.00 the output wire
will activate as soon as the launch wire is activated with 12v.
Duration: This setting can range from 0.00-30.00sec. This setting determines how long the output
wire will remain active after the Activation Point setting has been met. This setting will start counting
down after the launch wire has been released (in the event the Activation Point is set at 0.00).

INSTALLATION INSTRUCTIONS
Figure 4
Example: If the Time Switch function is used with an electric shifter to shift the transmission into 2nd
gear or High gear 0.70 seconds into the run with a duration of .030, figure 4 illustrates how the function
works in relation to time figure 4. For most shifter applications 0.25-0.30 seconds is adequate time
for the transmission to shift. Setting the duration with a lower time could cause inconsistent shifting
issues. Setting the value higher could cause issues with wasted CO2 (Air shifter) or a stuck plunger
(electric shifter). In most cases the shifter gate will prevent the shifter from advancing further without
the shifter plunger returning to the static position (Figure 4).
Note: Both the RPM and TIME Switch settings can be enabled at the same time. If both are enabled
at the same time, both RPM ON and Activation Point settings must be met before the output
wire will activate to ground. Be aware of the settings when both the timer and RPM settings are
enabled as the duration timer will start at the activation point regardless if the RPM condition
has been met or not. This can lead to erratic output wire results.

Data Acquisition: There are two settings for this function Enabled/ Disabled. Default value is Disabled.
To activate the Data Acq. function change the value to Enabled. This enables the capture of the output
wire activation in the MSD REVIEW only (Figure 5).
