1.5 Introduction

The PC6-RPO enables the user to carry out checks on pressure transducers, transmitters, pressure switches, pressure gauges and process indicators quickly and accurately. It is intended for use as a portable , on-site calibrator, used in close proximity with the equipment under test and without the need to remove the unit from its parent system. This section describes the connections to be made when checking switches, transmitters, etc. It also lists menu options, selection procedures and purpose of options available.

1.6 Connections

1.6.1 Pressure Input The PC6-PRO measures pressure

directly via the connector found underneath the case (i.e. the connection between the PC6-PRO and a hand held pressure test system). Alternatively, connect the item under test to the PC6-PRO with the adaptor and seals provided.

1.6.2 EPM (External Pressure Module)

Different pressure ranges can be read by attaching an External Pressure Module to the 14-way socket.

(See Fig.3 opposite)

Warning: The PC6-PRO must be switched off prior to

connecting or disconnecting EPM .

1.6.3 Voltage / Current Input / Output Voltage and Current

readings can be taken by connecting the outputs from the item under test to the 'V' or 'mA' and 'GND' input sockets on the connection panel using the connection leads provided.

Warning: When measuring voltage or current, make sure 'GND' is connected (where applicable, see fig. 3a)

1.6.4 Switch Test The switching pressure of a pressure switch can be monitored by connecting the contacts of the pressure switch between the INPUT 'GND' and 'SWITCH' sockets on the connection panel and pressurizing the pressure switch.

1.6.5 RS232

If the RS232 facility is to be used then connections to the 8way socket must be made to the specifications given in the table below. Alternatively an RS232 communication cable can be purchased from SI suitable for most RS232 applications as shown below.

RS232 Output

Connect the PC6-RPO to a printer or computer using a suitable cable (not supplied) as detailed above and set the parameters as detailed in Para. 2.6 & 2.8. The output can now be obtained as ‘single shot' or ‘timed' as follows:

Single Shot

when RS232 status & Log status are OFF. The output is obtained each time the key is pressed (provided any previous output

- This output is always available in Display mode

LOG

is complete).

Warning:

The PC6-PRO must be switched off prior to

connecting or disconnecting the RS232 cable.

Timed

status is ON & Log status is OFF. The output cycle is initiated by pressing the key. Pressing the key cancels the output.

- This output is available in Display mode when RS232

LOG

Once initiated, the output is repeated at the selected time interval (see ‘Event' function, page 26 ) until the key is pressed.

1.6.6 DPM

(DIgital Pressure Module) An alternative to the EPM,

the DPM communicates via the RS232 socket and is available in

-1 to 1000bar/15,000psi pressure ranges with accuracies up to

0.025%

1.6.7 Battery Charger

The internal battery pack may be recharged (when indicated by the battery low message) by plugging the charger (supplied) into the 'CHARGER' socket.

CAUTION:

When recharging internal batteries, only the charging

unit supplied with the PC6-PRO should be used.

1.6.8 Voltage Output

A voltage of +10V or +24V may be sourced from the PC6-PRO by connecting to the 2mm sockets. A typical application for this voltage output would be to power a pressure transmitter. ( see Fig. 3. page 10 ) To switch on voltage output function:a) Press the key twice to activate 'Set' menu. b) Select 'V-out' and press the key. c) Select 'ON' and press the key.

1.7 Messages & Parameters

The PC6-PRO registers pressure input at switch on after the initial startup message. The pressure reading is displayed on the top line of the LCD (see Page 3). Pressure values are monitored, alarm values are compared, alarm warnings and other information messages displayed until the unit is switched off.

Memory Errors:

Any read / write errors to memory detected at switch on will be reported as: Memory Error ‘Error No.’

Error Numbers:-

- Onboard eeprom; - IPM; - 2nd Onboard eeprom.

089

Errors with Pressure Modules will be indicated by the message "No P1 (P2 or DPM) proceeded by "PM EEPROM ERROR" at power on.

When switched on, the unit registers the same state as when last

1.7.1

switched off. The display mode (Operating/Set), units of measurement, function and parameter settings, alarm limits and RS232 output control, EPM selection, logged parameters are all retained at switch off, with the exception of the following conditions:

A battery low state occurring prior to the switch off. When switched

1.7.2

on, the unit registers the latest retained set of parameters.

Any TARE value set during use is not retained and therefore

1.7.3

should be set, if required, each time the unit is switched on.

Maximum and Minimum values are not retained. Current values

1.7.4

reflect pressure monitored from the start of the pressure input.

If the unit is switched off during a LEAK test then the test will be

(Bleep rate 1 Hz). ‘Low Battery' occurs when internal battery pack drops below 5.5V. Message flashes for 4 seconds, after a further 30 seconds, low battery detection is re-enabled.

1.7.10 Pressure Switch State Change (Bleep rate 2 Hz) Occurs in pressure mode with the pressure switch state display being

selected. When the connected pressure switch changes state, the pressure value (upper line) is frozen and the pressure switch state (lower line) display is flashed at 1 Hz unless a log file is open. Normal display update resumes when the key is pressed.

1.7.11 Printer Busy

ENTER

ZERO

(Bleep rate 1 Hz)

If the receiving device is not ready for input (e.g. device not connected or handshake LOW), 10 seconds after starting an output cycle (single shot or timed output) the message 'Printer Busy' is flashed on the display, together with an audible warning. If the device does not accept input within the next 5 seconds then the output cycle is cancelled and output is stopped until the key is pressed again.

1.7.12 Outside User Set Alarm Values

1.7.14 Connection Fault:

In voltage / current source mode, if the PC6-PRO is unable to control the voltage/current output (e.g. because there is no loop back in the current mode), the message “Connection Fault” will flash on the lower line accompanied by a bleep at 1 Hz. The message will continue until the fault is rectified or the user exits from source mode.

1.7.15 Short Detected:

If the 24V output is ON and it is shorted to 0V, the message “*Short detected*” will be displayed on the lower line accompanied by a bleep at 1 Hz. This message will be cleared when any key is pressed. In this condition the 24V supply will be switched off for safety.

1.7.16 Voltage / Current Overscale:

In Voltage measure mode, if a voltage in excess of 55V is connected to the PC6-PRO the message “*OVERSCALE*” will be displayed on the lower line, until the voltage falls within the input limits. In Current measure mode, a current in excess of 55mA enters the mA terminal, the PC6-PRO will display “*OVERSCALE*” on the upper line and the lower line will scroll the message “Check connections: Press MENU to continue”. Pressing the key will remove the message

provided the current measured is within range. This message may also appear in the source mode under connection fault conditions. Source mode will change to measure mode for safety. If the current overscale message occurs when the PC6-PRO is in timed RS232 output mode, the unit will exit from the timed output mode. If there is an excess voltage at the mA input when the PC6 is placed into current measurement mode, the message “Connection Fault” will be scrolled on the lower line. Once the fault has been rectified, press the

key to return to measuring mode.

1.7.18 Alarm Flags

A single character is output to indicate the various

pressure alarm conditions as given below:

* overload pressure level exceeded

(pressure warnings, 1.7.8 & 1.7.12) > pressure exceeds user set high limit < pressure below user set low limit “ ” a space if no alarms apply. c connection fault s short detected

Note: If two (or more) conditions occur which require a message display, the highest priority condition in the above list will be displayed. The sequence of messages given above set the priority except 'Switch Off' which comes last.
