Alarm Valid- This value is set to a default of 0 seconds. This is the amount of time an alarm
condition must be present for an actual alarm to occur. In certain processes with rapidly
changing pressures, this value can be changed to prevent undesired false alarms. Press the
SELECT/PROG with Alarm Valid selected.
Use the RIGHT ARROW button on the keypad until you get to the digit that you want to
change. Use the DOWN ARROW/UP ARROW buttons on the keypad to change the values.
To change a digit from a numerical value to zero, change the value to a zero. When the correct
value has been selected, press the SELECT/PROG button and the value will be confirmed. To
escape from this menu without changing the value, press the BACK button and the main
channel menu will appear.
Comm Port- Indicates data output function. There are several settings but the only active
settings are Off and Serial Report (Sio Report). If Off is selected, no data for the selected
channel is sent out the Serial Port. If Sio Report is selected, data is sent out the Serial RS232
port at the frequency programmed in the Global Settings Menu (contact PendoTECH for more
details on data collection from the PressureMAT). Press the SELECT/PROG with Comm Port
selected. The port settings are:
9600 baud
No Parity
8 data bits
1 stop bit
No flow control
Use the DOWN ARROW/UP ARROW buttons on the keypad to change the settings. When
the correct setting has been selected, press the SELECT/PROG button and the value will be
confirmed. To escape from this menu without changing the value, press the BACK button and
the main channel menu will appear.
The command AZK<cr> can be also used to generate a report as desired. The unit operates
using half duplex request-and-reply protocol; after sending the request, DO NOT send anything
else until the resulting expected response is received. THEN the requestor is free to proceed.
(ie, send one AZK<cr>, THEN make sure a successful response is received).
Note: See Appendix C on Data Collection to a PC
Time Alarm- This value is set to a default of 000 hours. This can be set to trigger an alarm in
a set period of time and most likely will remain at 000 hours which indicates it is not active.
Press the SELECT/PROG with Alarm Valid selected.
Use the RIGHT ARROW button on the keypad until you get to the digit that you want to
change. Use the DOWN ARROW/UP ARROW buttons on the keypad to change the values.
To change a digit from a numerical value to zero, change the value to a zero. When the correct
value has been selected, press the SELECT/PROG button and the value will be confirmed. To
escape from this menu without changing the value, press the BACK button and the main
channel menu will appear.
