    Two fail-safe relay output contacts provide an alarm if a temperature probe fails, a temperature is outside the acceptable range, the processor fails or power is seriously depleted or cut off. If the TA-1000 Plus is equipped with analog inputs, the relay output will also signal an out-of range input. If equipped with a net pulse output option, the device can be used to transmit a compensated volume to another device.

    The terminal housing must be installed at the factory. The addition of a terminal housing to an existing device violates CSA certification regulations. Figure 1.2— TA-1000 Plus explosion-proof package with optional terminal housing Display The display provides a real-time readout of process temperature (measured by the probe), average tempera- ture, total counts, counts per hour and alarm count.

  • Page 33: Configuring Analog Inputs

    Analog inputs are optional features. The following procedure pertains only to devices purchased with this op- tion. The TA-1000 Plus supports up to two analog inputs. Each can be configured for a 0–5 VDC, 1–5 VDC or 4–20 mA signal and can be used to receive readings from a pressure transmitter, densitometer or BS&W de- tector.
  • Page 34 If the BS&W live reading goes above the divert setpoint value or goes outside the configured range, the TA-1000 Plus’ delay timer will be activated. If the value remains out of tolerance at the end of the delay period, flow will be diverted to a holding tank, flow loop, etc. If the value comes back inside the tolerance and remains there for 1/10th of the configured delay period (for example, 9 seconds when the time delay is set for 90 seconds), the divert valve will close and the timer will stop.

  • Page 37: Configuring Outputs

    Digital Output The TA-1000 Plus is equipped with two mechanical SPDT relays that can be configured for use as an alarm or as a means of diverting flow when the TA-1000 Plus is used for BS&W monitoring. TA-1000 Plus alarms may be activated by probe or probe wiring failure, faulty temperature circuitry or an out-of-range measure- ment.

  • Page 38: Configuring A Custom Probe Fail Alarm

    By default, a probe fail alarm is generated when the process fluid temperature falls below or rises above the probe operating range. However, some applications require the user to take action before the temperature reaches these levels. The TA-1000 Plus allows the user to determine custom low and high setpoints for trig- gering a fail alarm.
