Data Sheet : Press Man

MO TRON

Description Picture

Press Man is a simple but yet efficient controller for maintaing constant pressure in heating and ventilation environments. It is charactized by a very robust construction and extremely simple user interface. controls the HVAC pressure from an pressure transmitter with an analog output mounted directly in the ventilation system. Difference pressures can be obtained by incorporating mecanical blends etc. IP54 grade and integrated keys / display makes Press Man well suited for many applications. Press Man

MO TRON

has a setpoint, which is controlled by the arrows. A single press will put the setpoint one up or down, holding the arrows will make the setting change fast while pressed. Measured pressure will be displayed apr. 5 sec after keys have been released
PRESS MAN Press Man Press Man has two relay outputs, the first is used on ON/OFF by the key setting, the other is used for alarming. ON/OFF is activated as the key is activated, the alarm output will be active when the output can not be reached whithin 30 minutes !. Means, that if the output internally is UNDER or OVER the MIN/MAX settings, the relay will activate. Flashing LO or HIGH in display Press Man can indicate the real output for the attached speed controller, OR, it can indicate the real input from the attached pressure transmitter. Both values will indicate in percentage (0-100) of input and output) Press man
ONOFF can be 100% stopped, pressing the ON/OFF button. Display will indicate OFF and the DC output will be forced to 0, as will be the 2 relays. Press man PRESS MAN can be SCALED to one of 4 ranges by POWER UP. This will make it very useful for different industrial pressure transmitters on the market today. It will be compatible with Motron PS1000 scaleable pressure transmitter. It comes with an standard ac/dc supply interface, 0-10V output and dipswitch settings for 150 - 300 - 500 - 1000 Pa
SHOWOUT PBAND SHOWIN has individual settings for minimum and maximum speed for the attached speed controller. Settings to be controlled by MIN/MAX buttons. Parameters for Proportional Band and Integration Time is done from the keypads as any other parameter. The PI regulator will meassure the pressure, compare it to the setpoint and try to maintain the dc output to make the real pressure as close to the setpoint as possible. On power up, version and range information is presented shortly in display.
