PPCH-G v1.02i Embedded Software

Run Winflash and select the file downloaded as the file to write to the product.

Make sure the correct COM port of the product is connected to a RS232 port on the host PC. Use a null modem cable to COM2 port of PG7000 Piston Gauge. Use a standard RS232 cable to COM1 port of PPC, PPC, RPM and molbox.

If your product has an model number ending in "-AF", it requires specific "-AF" embedded software.

The updating of embedded software should only be performed after given specific instructions to do so from a Fluke Calibration Authorized Service Center.

If the update isn't performed properly, your product will be inoperable until it is.

Ver 1.02g (2018 Mar 15)
FIX (PPG-91): Default range units for the US and SI models were inverted. US model default range units were changed to psi and SI models were changed to MPa.

Ver 1.02f (2012 Apr 04)
FIX (PPG-91): Default range units for the US and SI models were inverted. US model default range units were changed to psi and SI models were changed to MPa.
FIX (PPG-90): PPCH is now compatible with alternate front panel display hardware.
FIX (PPG-86): PPCH-G can experience large overshoots of target if the valve opening routine doesn't detect an open condition during the valve open seek routine.
FIX (PPG-92): Control can stall in high volume dynamic control mode when control fails to hand over control back to the initial valve after the first handoff to the opposing valve when the valve reaches and stops at its closed point.

Ver 1.02c (2007 Oct 26)
CHG: Improve valve configuration sequence, selects best 2 out of 3 runs.
FIX: In high volume dynamic mode, control can overshoot target in which case controller would restart generation.
FIX: In high volume dynamic mode, pressure may oscillate at or around target.
FIX: In high volume dynamic mode or standard dynamic mode, pressure may change suddenly when approaching target, sometimes resulting in overshoot.

Ver 1.02b (2007 Jul 20)
ADD: Add support for 20M and 40M utility sensors
FIX: Upward pressure excursions in high volume dynamic mode may suddenly overshoot target.
FIX: “PCAL:HI?” and “PCAL:LO?” commands respond with ERR#6.
FIX: MODE command response does not include "MODE =".
FIX: Response to TP command does not update (to 0) after a VENT.

Ver 1.02a (2007 Feb 16)
FIX: Privileged command "!STEPHOMEx" malfunctions, always sending the outlet valve to the stop, not the selected valve to the stop and back home. (THIS FIX DOES NOT AFFECT REGULAR PPCH-G OPERATION).

Ver 1.02 (2007 Jan 15)
ADD: Passing UL shuts off the supply (valve 1).
ADD: Force a Not Ready indication during TPCU reset.
ADD: Improved volume determination in TPC configuration.
CHG: Valve control during TPC reset and effectiveness of reset improved.
CHG: Rezero valves after user and emergency aborts.
CHG: Control during standard dynamic control should not be READY until the TPC is controlling
- not during valve control.
FIX: Internally generated "auto" TPC configuration can be triggered when it should not.
FIX: If the volume argument is specified in a remote pressure set command then TPC autoconfiguration
should not run even on regeneration/TPC reset.
FIX: Possible error in valve configuration opening point calculation.
FIX: Change menus from "TPC config" to "Volume config".
FIX: Remote to local transition can lead to bad valve control or overshoot.
FIX: Vent light stays on if a remote to local operation occurs while venting remotely, even though
the unit has aborted and is not vented.
FIX: User and emergency aborts should take the valves to default home position.
FIX: Prevent premature valve to valve handoff during TPC reset.
FIX: Prevent valves from closing all the way to the zero position during control.
FIX: Very small excursions in standard dynamic mode should use TPC only.
FIX: Prevent upward ramp pressure control while the UL is tripped.
FIX: Improve TPC control and make scaling independent of valve control.

Ver 1.01a (2006 Jul 10)
CHG: Unit change using the remote "UNIT=" no longer assumes gauge mode. It stays in the existing
measurement mode.
CHG: Remove volume scaling from high volume dynamic mode freeze rate calculation.
FIX: Control in High Volume Dynamic mode sets and holds pressure slightly below target when descending.
FIX: Vent valve could open during vent process at high pressure during factory configuration
FIX: Escape from remote to local while ramping leaves RPT measurement in "fast" (200 ms) while
generation is aborted.
FIX: Changing user level can cause Pmax indication with utility sensor PPCH-G.
FIX: Error in valve configuration opening point calculation
FIX: Vent operation would not get ready if pressure error was too great.
FIX: ARANGE remote command is ignored and returns ERR #6 most of the time.

Ver 1.01 (2006 Feb 21)
Intial release of software for a new product.
