Waiting to Start, Active or Completed. Once SNTL150P terminal voltage has
increased above boost initiate voltage, then this will become green.
Commissioning Charge – When SNTL150P is first powered up, it will automatically
enter a prolonged boost extension period, factory set to 6 hours, once complete this
will become green and be marked as complete.

Input Status (if option fitted) – Shows indication of SNTL150Ps digital input
Output Status – Shows indication of SNTL150P self-resetting output protection

circuit

Time in Float Mode

Time spent with charger in its float mode of operation

Time in Boost

Combination of all time spent both in SNTL150Ps
ramping to boost stages as well as Boost Extension
Periods, including commissioning charge times.

The central pie chart shows a breakdown of time spent by
SNTL150P in its 5 key charge states.

Charger History screen – Recharge History

This provides an historic view of the last 15 bulk
charges in time.

The SNTL150P will record time spent ‘ramping

the batteries to their target boost voltage.
(recorded in 10 minute blocks)

The Bar Graph Display will provide an indication of
the trend of the battery recharge time, typically as
batteries chemical makeup weakens, the bulk charge
time will decrease, as the capacity of the battery
becomes reduced.

Note: Use with caution as a guide to battery health,
as the SNTL150P will only record time spent in this
condition, but not the batteries terminal voltage at
start of charge cycle.

The Battery check process reduces the output of
charger to nominal voltage and validates terminal
voltage.
During this battery check it will report Checking

Battery in the Active State window.

If no battery is detected, or battery voltage is less
than the configured Battery Detect Voltage then it
reports Battery Missing in the Fault State window.
The SNTL150P Performs a battery check at the
following instances:

 On AC Power Up, before entering boost mode

of operation

 After Completing a Boost Cycle
 Every 1 minute if battery presence is not

detected

 Every period of minutes as defined by Global

Charger Settings whilst in Float Mode of
Operation

Once charger is in Float mode, the charger performs
a battery check in accordance with the Battery Check

Period setting as configured in Global Charger
Settings

To change the interval time of the battery check
routine, enter required time in minutes into Battery

Check Period and select Download To Charger to

SNTL150P

Note: When download a new interval time, the
changes will take place immediately. To disable

battery checking, enter “0” as Battery Check Period

and update charger.

The SNTL150P can also be configured to turn its output
off for up to 30 seconds when performing battery
check. After this period has elapsed, the SNTL150P will
measure its own DC supply voltage and in accordance
with Battery Detect Voltage will report Battery
Missing status.

Should the SNTL150P report a battery check, it will
continue checking every 1 minute for battery until
fault has cleared. Once a battery is detected it will
revert to Battery Check Period time
During a Battery Missing Alarm the SNTL150P will
behave in accordance with the parameters set in

Battery Missing Action. The SNTL150P’s output can be

turned off, or set to a specified level.

Battery Check Routine

SNTL150P-PCSUITE installation & operation

ci0052 p22/28 issue 2 2014-01-09

The SNTL150P maximum output current can be
limited to a value as set within the Current Limit field
in Global Charger Settings.
Note: If battery voltage is below minimum charger

output voltage (typically 10V on a 12V unit and 20V on
24V unit) then the SNTL150P will be limited by
demands from battery and hardware current limit
control (5A)

Boost Drop Out Current

The alarm output can be set to hold off fault reporting
for up to a maximum of 240 seconds (4 mins).

The SNTL150P will terminate its Boost cycle if the
output current has dropped below a preset level. This
prevents needless battery gassing and temperature
rise, once the battery is fully charged.

Configurable Boost Drop-Out Current between 0 and
5amps to a 0.1A resolution, the option to disable this
feature can be done by ticking the checkbox marked
“Disable Boost Drop Out On Current”

The SNTL150P employs a configurable option to allow
an auto-boost cycle to occur without the need to
manually engage it. Should the charger not have
recorded a boost cycle happening within a given
period, it exercises the batteries, elevating their
terminal voltage, recombining the partly separated
water and strong sulphuric acid within the cells,
preventing build up on the battery plates and
maintaining battery life and performance

The digital input can be configured to make SNTL150P
behave in a given manner.

The following options are available:

Return To Float Mode

Single Input Action, forcing charger back to Float.
(Once actioned, the input needs to be released and re­triggered for it to act again)

Ramp To Boost

Single Input Action, forcing charger through a full boost
cycle

Boost Extension

Single Input Action, forcing charger into a timed boost
extension cycle

Perform Battery Check

Single Input Action, forces SNTL150P to perform a
battery check

Reduce to Nominal Voltage

Held Input Action, reduces the output voltage of
SNTL150P to its nominal value. (12/.24V) SNTL150P
will remain at this level unit either:

 Input is released
 A Short Circuit / Reverse Polarity Fault occurs

Turn Output Off

Held Input Action, turns the output off from the
SNTL150P. SNTL150P will remain in this condition until
either:

 Input is released
 A Short Circuit / Reverse Polarity Fault occurs

Note: Should only High Alarm be configured to

alarm, then SNTL150P will inverse the logic of

the relay and cause it to energise on fault.

This prevents mi-interpreted readings from

Maximum address number to as low as possible.
Currently the SNTL150P has a fixed address of 100.
These settings have no effect.
