FAN SPEED CONTROL OUTPUT
The BreatheSafe INPRESS TS controller automatically adjusts the
turbine motor to maintain a pre-set cabin pressure based on the
unit's pressure set-point.
The TS unit monitors the cabin pressure as measured through its
built-in pressure transducer and calculates the error based on the
pressure setpoint. This value is applied to an algorithm and the
controller calculates a proportional output which adjusts the speed of
the pressuriser motor.
MOUNTING
The TS unit is designed to be dashboard mounted and utilizes a
proprietary housing to secure the unit. Mounting can be in any
orientation, preferably internally and positioned such that the
operator can monitor the cabin pressure, ensuring their working
environment is safe.

SUPPLY POWER

Issue Date:
The BreatheSafe INPRESS TS unit is designed to operate via the
vehicle's ignition key-switch. The unit becomes fully operational
approximately 5 seconds after turning the ignition on.
It is advisable to install an inline fuse rated at 5A maximum for added
protection up to the unit's connector. The unit is fully protected
against reverse power for an indefinite period.
The operating voltage is in the range of 12V to 36V dc and the
power supply is designed specifically to operate in the harsh vehicle
environments, which may include battery jump starts and battery
chargers. The door and window digital inputs operate in the range of
12 to 24V dc commensurate with the vehicle's power supply.

CALIBRATION
The BreatheSafe INPRESS TS controller is fully digital and should
not require further calibration or setting up. The unit becomes fully
operational approximately 5 seconds after being switched on.
For added peace of mind, auto calibration is available under the Zero
Sensor section.
Please do not attempt to open this unit and tamper with it as there
are no user serviceable parts inside and you may cause it irreparable
damage in the process.

CONTROL OVERRIDE

At the back of the INPRESS TS unit there is a small switch, this will
turn off INPRESS control and run High Pressure Air Filtration unit by
itself at full speed.
We do not recommend this.
