The Tmax system includes 2 Piston Tanks type XP with AutoStop & proportional Trim, proportional control unit Tmax2 and pressure switch as well as all necessary components, such as hoses, outboard connectors and wire leads.
Control unit Tmax offers a maximum of features for controlling Piston Tanks. Tmax version 2 (V2) is equipped with a regulated power supply for the processor, by which susceptibility to radio interference is minimized.
The Tmax System can be operated via one, two or three R/C channels. However, for implementing all functions of the system three R/C channels are necessary. This setup will require an analogue switch (3 positions: on/off/on) and two proportional slider switches.
The Tmax features 3 fail safe devices: 1. automatic resurfacing if max. depth is reachend (via pressure switch #5028) 2. loss of signal (adjustable to 4 or 7 sec.) 3. low battery monitor
The maximum operational depth is limited to about 1.8 meters by the pressure switch included. The pressure switch is an integral part of the system and should not be sacrificed. Furthermore, the Tmax offers additional fail-safe features such as battery monitor and loss of Tx-signal.
With the voltage dropping below the preset minimum current, the piston tanks will start to press water out of the cylinders. If this is the case, the bow-sided tank will start to press out ballast water first. After a pause of about 15 sec. the stern tank will start to blow. This sequence minimises the strain on the already weakened battery pack.
The different modes of the system is indicated by LEDs. The operational circuit is equipped with a fuse protection.
Piston Tanks Type XP feature the AutoStop as well as proportional fine trim meaning that the last 30 mm of piston travel can be proportionally controlled by the transmitter. AutoStop means that the drive unit will stop as soon as the tank (cylinder) is fully emptied or filled.
Please note: Customized Piston Tanks If you are looking for a dive system with Piston Tanks and a volume not listed here, we can manufacture any volume starting from 250 to 1000 ml at a surcharge of EUR 47.60 (40.00 net) per system added to the smallest tank volume (i.e. Tmax 500 in 6 or 12 V). Take a look at our download section, where you will find Piston Tank Meassurements as PDF. Please note that outside diameter of 75 mm never changes; only the length of the cylinder is variable.
