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.
TA-1000 Plus Temperature Averager Section 1 Temperature The temperature input is a single-element probe sold by Cameron. The dual-channel TA-1000 Plus device will accept inputs from two probes. Flow Flow input pulses may be 9–30 VDC pulses, 120 VAC pulses or dry contact closures.

The correction calculation uses API MPMS Chapter 11.1 to calculate the volume correction factor (VCF) of crude oil using the entered API gravity and average temperature, for a temperature base of 60°F and a pres- sure base of 14.73 psia.

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.

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.
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.
TA-1000 Plus Temperature Averager Section 4 separate out in a holding tank as the temperature cools. The ability to establish an alarm when the process fluid is approaching the paraffin melting point allows the user to better manage this risk.
Disabling the Pulse Input Filter The TA-1000 Plus contains two built-in noise filters that improve the accuracy of counts in systems where pulses are generated less than once per second. If pulses are generated faster than once per second, however, performance may be improved by disabling the filter as follows: 1.
TA-1000 Plus Temperature Averager Section 4 4. Press INCREMENT to change the PulseIn1 Filter setting to “Disable.” 5. Press ENTER to accept the change and advance to the PulseIn2 Filter menu. Again, the bottom readout should display the default setting, “Enable.”...
5. The display should indicate “0” to verify the alarm is cleared. Clearing Input Averages When analog inputs are enabled, the TA-1000 Plus will continuously average input values and display those averages. It is recommended that these values be zeroed each time the user resets the probe counts and totals.

Obtaining Technical Assistance Knowing which functions are enabled in a TA-1000 Plus is key to a Cameron technician’s ability to trouble- shoot a suspected malfunction. Enabled functions are identified by a factory-programmed function ID, which is easily retrieved from the device if the processor and display are functioning. Before contacting Cameron to report a suspected malfunction, please retrieve your device’s Function ID as follows:...

Selecting the Probe Type Note By default, the TA-1000 Plus is configured for use with a single-element probe. When a dual-element probe is used, the probe type change is important because of differences in the temperature ranges of single-element and dual-element probes. If the configuration change is not made, the TA-1000 Plus values will be inaccurate.
