DP1: Engine overspeed shutdown level
DP1 is a 16-way digital potentiometer that, with DIP switch S5, allows the setting of an engine overspeed shutdown level. If the actual
engine speed (determined by ECU-transmitted J1939 data) exceeds the set level, CANstart initiates an engine shutdown. Note: the
CANstart overspeed feature operates in addition to any ECU overspeed protection.
CANstart model 9631 provides overspeed settings between 1250 and 2750 RPM (in 50 RPM increments) for general purpose, variable
speed engines. Model 9632 allows settings of 1 to 15% above either 1500 or 1800 RPM fixed speed engines, e.g. as used in 50 or 60 Hz
gensets. On both models, the overspeed protection can be set to ‘off’ (i.e. disabled).

Electrical Connection
Electrical connection to 0.5 – 1.5 mm² / 16 – 20 AWG panel wiring
is through a 14-way, two-part (removable) screw terminal block:
Typical connection
 Pre-strip 8 to 10 mm / 0.3 to 0.4 in. of insulation from each wire.
 Insert wire(s) into the correct terminal receptacle, ensuring
insulation is clear of the terminal.
 Tighten the terminal screw using a 3mm flathead screwdriver,
ensuring the wire is secure.
General connection recommendations
Murphy make the following recommendations for the electrical
connection of engine and generator controllers.
 Minimise controller output load current (i.e. wear/tear and
potential damage) by using slave relays between the controller
outputs and high power end-devices, e.g. starter solenoids.
 Suppress (at source) electrical interference from panel relay
and engine solenoid coils, using flywheel diode or proprietary
snubber/suppression components as appropriate.
 Use separate routing for AC and DC wiring harnesses.
 Use separate wiring for a) connection of battery charger to
battery, and b) connection of battery to panel DC supply.
Separate wiring will reduce high frequency battery charger
output noise on the panel DC power supply.
Terminal functions
6
Charge fail
The charge fail ( ) LED lights, but there is no shutdown
or alarm output, when pin 6 is connected to battery
negative. When using a charge alternator, connect pin 6 to
the alternator warning lamp (WL) terminal. Note: pin 6
supplies the alternator excitation current.
7
8
Auxiliary 1 fault input
Auxiliary 2 fault input
These inputs allow engine shutdowns to be triggered by
remote switch or relay contacts. Connection of these inputs
to battery negative causes deactivation of the Run output
(pin 3), activation of the alarm output (pin 5) and the flashing
of the Aux fault ( ) LED – see operation section for details.
Pin Function
1
2
3
4
Negative DC power supply
Positive DC power supply
CANstart operates with any smooth DC / battery voltage
in the range 8 – 32V. Supply brown-out protection is fitted
as standard. Connect a 5 Amp anti-surge fuse in the
positive DC line (pin 2).
Run (ECU) output
Start (crank) output
These outputs provide control signals for the engine’s
ECU Run input and starter motor. Both outputs use
solid-state FET devices, which give a positive DC signal
(rated 6 Amp max) when active.
The Run output (pin 3) is used to control the ECU Run
input. Before connection, check the engine documentation
for ECU Run input polarity requirements. If the ECU
requires a switched negative/ground or ‘open to start’
connection, use an interposing relay with suppressed coil
between pin 3 and the ECU Run input.
Pin 3 activates as soon as the key is switched to the I
(RUN) position, and remains at positive DC as long as the
engine is required to Run. Pin 3 de-activates if the key is
switched to O (off/reset), if the ECU transmits an engine
shutdown fault code, if a CANstart auxiliary fault input
is activated, or if the overspeed fault levels are exceeded.
The Start output (pin 4) operates when the operator
switches the key to the (spring-loaded) II (start) position.
A slave relay with suppressed coil is recommended
between pin 4 and the starter motor solenoid coil.
5
Alarm output
The alarm output activates during fault conditions,
triggered either from the ECU-transmitted J1939
message, or from CANstart’s auxiliary inputs or
overspeed shutdown feature.
Pin 5 is an open collector transistor output: activation
gives a negative DC signal rated 250mA @ 32VDC max.
The output typically drives a relay coil, which in turn
drives an audible or visible alarm. A flywheel diode or
other suppression device should be connected across all
relay coils - see ‘typical connection’ above.
CANstart™ 9631/9632 installation instructions
To reset an auxiliary fault condition, turn the key to O (Off)
or remove the DC power supply.
9 Oil pressure gauge output
10 Coolant temperature gauge output
11 Tachometer output
These outputs can be used to drive a tachometer and
electric gauges, based on ECU-transmitted J1939 engine
data.
Pins 9 and 10 give a variable current output for driving
oil pressure and coolant temperature electric gauges.
The outputs can operate with several different
manufacturers’ gauge types, as set using DIP switches S1,
S2 and S3 - see Configuration Settings section above.
Pin 11 gives a square wave output (0V to battery positive
DC) with a frequency proportional to engine speed. At 1500
RPM engine speed, the output frequency is approximately
121 Hz, suitable for driving charge alternator based
tachometers such as the Murphy AT(H)A series. Pin 11
gives no output below 100 RPM engine speed.
Connect each output to the appropriate gauge and
tachometer signal input terminals. Connect gauge and
tachometer negative terminals to battery negative, ideally
via dedicated wiring to CANstart pin 1. (The use of
dedicated return wiring to pin 1, rather than via a
chassis/ground return, minimises gauge inaccuracies
caused by ground noise.)

Electrical Connection (cont.)
12 CAN shield/screen
13 CAN High
14 CAN Low
These connections receive ECU-transmitted J1939 CANbus
data, including engine parameters and fault codes. Wiring
and connection should be made in accordance with the SAE
J1939 standard and ECU/engine manufacturer’s guidelines.
Attention should be paid to the wiring type (usually twisted
pair, often with a shield/screen), and to the shield/screen
ground connection (normally only at one end of CANbus
network, often at the ECU).
CANdrive™ is supplied with a 120 Ohm CANbus terminating
resistor in circuit. If CANdrive™ is not located at the end of
the CANbus network, switch out the terminating resistor
using DIP switch S4 - see Configuration Settings above.
Operation and Maintenance
Operation
Overspeed fault. Lights continuously following an
overspeed shutdown fault (whether triggered by ECU or
CANstart).
Operator control of the engine is through the 3 position keyswitch:
O
Off / reset. Removes DC power from the CANstart,
de-activating the Run (ECU) output (stopping the engine) and
resetting any CANstart fault conditions, e.g. overspeed or
auxiliary input.
I
Run. When the key is switched to I:
Charge fail fault. Lights continuously during a charge fail
condition, whenever CANstart terminal 6 is connected to
battery negative. If CANstart is used with a charge
alternator, the LED also lights when the engine is
stationary (indicating that CANstart is providing charge
alternator excitation current).
 The Run (ECU) output activates, signalling the ECU that
the engine is required to run.
 The CAN LED lights, initially flashing, then continuous –
see ‘LED operation’ below.
 The charge fail LED lights – see ‘LED operation’ below.
General fault. Lights in response to both ECU-transmitted
J1939 fault messages and CANstart auxiliary inputs:
 Continuously lit indicates an ECU-initiated fault
shutdown
 A regular 50/50 on/off flashing indicates one or more
ECU-transmitted fault warning messages. The LED
goes out if the ECU stops sending fault messages.
The Run (ECU) output deactivates:
 If the ECU transmits (and CANstart receives) a J1939 fault
shutdown message – see ‘LED operation’ below.
 One short flash followed by a long pause indicates an
engine shutdown triggered through CANstart’s ‘aux 1
fault’ input.
 If engine speed (from ECU J1939 data) exceeds
CANstart’s overspeed limit, as set by S5 and DP1.
 If a CANstart auxiliary shutdown input is activated.
II
 Two short flashes followed by a long pause indicate an
engine shutdown triggered through CANstart’s ‘aux 2
fault’ input.
Start. Activates the Start (crank) output. Keyswitch position II
is sprung-loaded to return to the I (Run) position.
LED operation
Power / CAN status:
 Lights continuously when CANstart is powered and
valid J1939 CAN messages are present.
 Flashes if CANstart is powered, but no valid CAN
messages are detected.
Oil pressure fault. Lights in response to ECUtransmitted J1939 messages:
 Lights continuously following a shutdown fault
 Flashes during a warning only fault.
Coolant temperature fault. Lights in response to ECUtransmitted J1939 messages:
 Lights continuously following a shutdown fault
 Flashes during a warning only fault.
