WARNING AND CAUTION
WARNING
WARNING refers to possible injury to the user or significant damage to the meter if the user does
not follow the procedures.
CAUTION
CAUTION refers to restrictions and rules with regard to preventing damage.
WARNING
Verify that all AC sources are disconnected before connecting or disconnecting the current
transformer. Failure to do so will generate lethal voltages on the current transformer.
If you are not knowledgeable about electrical systems, have an electrical professional install this
unit. The diagrams in these instructions pertain to the installation of the 600-ACSM and not to the
overall wiring of the vessel.
If an inverter is installed on the vessel, its power leads must be disconnected at the battery before
the unit is installed. Many inverters have a ‘sleep mode’ in which their voltage potential may not be
detectable with measuring equipment.
If an inverter is installed on the vessel, it must be stopped and rendered inoperable before the unit
is installed.
Verify that no other DC or AC is connected to the vessels wiring before installing the unit.
If the meter must be removed, connect the current transformer leads together before restoring
power to the AC system.
CAUTION
The back of the unit is not waterproof. Do not install where the back of the meter is exposed to
water.

Configuring Loadshed relay operation.
All three ‘Current’ status pages have the ability to drive the Loadshed relay output on the back of
the meter.
This is provided so the operator can automatically drop a NON-ESSENTIAL section of their AC
loads. Preventing a current rise to a level that will overload the ships generators and cause the
Circuit Breaker to trip and lose power to all AC consumers.
Wire the Loadshed relay as per the ‘Wiring Diagram’ at the front of the booklet, please note that a
snubber diode is required to be fitted across the relay coil for inductive loads.
Each ‘Current’ status page can be set at a different level but please note the output will be active
from the first ‘Loadshed’ becoming active until the last one clears.
To set the ‘Loadshed’ value, navigate to,
‘Main Menu’ > ‘Setup’ > ‘Input’ “required current status page” > ‘Settings’ > ‘Max Current’.
A default value of 40A is preset. Select ‘Max Current’ then enter then required value.

Chapter 3 Configuration
Page 16
The Load shed current has two timers the first one of which to expire will activate the Load shed
relay output.
The timers begin counting at different current levels and continue to count as long as current stays
above the set point. If it any point the current drops below the measuring point the timer will reset.
The first t1 begins counting as current rises above 120% of Max current. t2 begins counting when
current rises above100% of Max current.
The counter times are set to default vlaues. These can be changed by the following method.
Step 1. From the ‘AC Current Calibration’ select ‘t1 120% and/or t2 100%’.
Step 2. Use the soft keyboard to enter new timer value.
Step 3. When both the timers have been set you are able to ‘Enable Load Shed’ at the ‘Load shed’
function.
Alarms
All inputs have the ability to have a high or low warning alarm. Depending on what type of meter
configuration you are running, some of these alarms will be enabled by default.

Icon
When an alarm is active you will see an Alarm Window for each active alarm and the
buzzer/external alarm will sound. The Alarm Window will tell you which input is alarming and what
type of alarm it is i.e. Low On or Low Voltage. The label for all alarming circuits will be red also.
To remove the Alarm Window from the Status Page you have 2 options:
Disable the alarm
You will get no further alarms from this input until it is re-enabled.
Snooze the alarm

Chapter 3 Configuration
Page 17
The alarm will go in to snooze mode for the default time and will pop up again when the timer
expires and the input is still in an alarm state.
If there is more than one alarming circuit, a new Alarm Window will pop up after the previous alarm
is acknowledged.
Note: to avoid unwanted alarms on meter start up there is a 20 second delay after status screen is
loaded when alarms will not be active.
Alarm Icons
