Bargrafik Gösterge PMS-970T

The programmable PMS-970T indicator is applicable to cooperation with the transmitters having a standard current or voltage output signal. The measurement is also shown on a four-digit LED display and on a 26-point three-colour bar graph. Four alarm values controlling the relay outputs can be programmed. The alarm values are shown on the bar graph. Diodes on the front of the indicator indicate the exceeding of the alarm values. The device can use a linear characteristic or a multi-segment characteristic freely definable by the user. The meter can also be provided with an RS-485/MODBUS RTU digital output and with 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;
  bar graph mode: two-colour or three-colour.
