[. . . ] "DATE=yymmdd "DATE" yymmdd: The date in the numerical only format year-month-day with no spaces. The PPC2 AF has an internal real time calendar clock. It is used for date stamping calibrations. Command: "DATE=960221" Reply: "960221" ERR# 7: Missing or improper command argument(s) 3. 4. 4. 4 Decrease the pressure quickly. "DF=n" `0' Closes the fast down valves. Opening the fast down valves will cause the pressure to decrease quickly. Command: "DF=1" Reply: "DF=1" ERR# 6:The n argument is a `0' or a `1' 1. 2. 7 © 1998 DH Instruments, Inc. Page 60 4. REMOTE OPERATION DP= Purpose: Syntax: Arguments: Remarks: Example: Errors: See Also: DS= Purpose: Syntax: Arguments: Remarks: Example: Errors: See Also: DRVn (=) Purpose: Syntax: Arguments: Remarks: Example: Errors: See Also: ERR Purpose: Syntax: Remarks: Decrease the pressure a given amount using the slow speed. "DP=n" n The decrease in pressure desired (current pressure units). This can be from 0 to 2 % FS of the current transducer range. The slow speed will be used for a calculated amount of time (up to 5 seconds) to create the desired change. The PPC2 AF will not attempt to control the pressure to a target, so the change in pressure will be approximate. Command: "DP=10" Reply: "10. 00 kPa a" ERR# 6: The n argument is not within given limits. "DS=n" n `0' Closes the slow down valve. Opening the slow down valve will cause the pressure to decrease slowly. Command: "DS=1" Reply: "DS=1" ERR# 6: The n argument is a `0' or a `1' 1. 2. 7 Read or set the status of an external solenoid valve. "DRVn=x" "DRVn" n The valve to operate on. The PPC2 AF can control up to eight external valves. Valve driver #8 is reserved for the external SPLT valve. Command: "DRV3" Reply: "DRV3=1" ERR# 6: The n or x arguments are not within given limits. 3. 3. 4 Example: See Also: Read the last error message. "ERR" The "ERR" command finds out more details about an error that has occurred. [. . . ] In toggle mode the driver state will toggle each time the corresponding key is pressed. However, the total output of all the activated drivers cannot exceed one Amp. Therefore, if multiple drivers are being activated please refer to the following chart as a guide. # OF ACTIVE DRIVERS MAX CURRENT PER OUTPUT 1 2 3 4 5 6 7 8 500 mA 400 mA 275 mA 200 mA 160 mA 135 mA 120 mA 100 mA The male connector (P/N 102478) for the DRIVERS port is supplied with the PPC2 AF accessories. The following table and figure should be used as reference when building a cable to utilize the drivers port.
