Functions and use

The programmable PMS-970T indicator is applicable to cooperation with the transmitters having a standard current or voltage output signal. Measurement is visible on 4-digit indication and 26-point bar graph. Four alarm values controlling the relay outputs can be programmed. Alarm values are indicated on bar graph and exceeding of the alarm values is indicated by diodes on the front of the display. The device can use a linear characteristic or a multi segment characteristic freely definable by the user. The meter has RS-485/MODBUS RTU digital output and can also be provided with an a passive current output with programmable range of current variation.

The PMS-970T enables the following parameters to be programmed:

• measuring value display range and decimal point position;

• level and hysteresis of action of relays;

• relay operation mode: normally connected or normally disconnected;

• input signal conversion characteristic ¨ (segmental approximation, max. 15 segments);

• display filtering level;

• “alternating control of outputs” function used to balance wear ¨ on groups of pumps.

• two modes of bar graph: 2 and 3 color.
