ATC Component Overview (Atlas 8800 Only)
The ATC PCA (T20569) and T-Meter Module ATC (T19405) are optional electronic
components. Examples of probes and meters used for temperature control are primarily for the
Canadian market. The ATC option measures the temperature of the dispensed products and
compensates for changes in the product volume due to changes in the ambient temperature.
The T-Meter Module PCA links the thermal probe in the meter cover with the ATC PCA. An
Intrinsically Safe (I.S) barrier is used at the J-box between the T-Meter Module PCA and ATC
PCA.
115/230/380 VAC Single/Dual Unit with ATC PCA (T20569) and
Programmable Pump Preset (Option)
The ATC PCA (T20569) records the temperature-related input from the T-Meter Module
Hydraulic Interface PCA, which then modifies the pulser-count to regulate the temperature
change. The adjusted pulser-count is supplied to the Pump Controller PCA. Components for
the firmware are located near the center of the board at U5 and U11, which also contains the
battery-backed RAM. The PCA receives +5 VDC from the Pump Controller PCA and
14.5 VDC from the Pump Interface PCA. The ATC PCA also receives data from the Manager
Keypad before the Pump Controller PCA, which allows information to be entered through the
keypad for programming and testing purposes, when the ATC is used.
