Section 3
Operation
3-1 Introduction
3-1.1 The following paragraphs discuss the steps to take when first applying power to
the GDCP-A system. Also, discussed are the initial displays after start-up, the
default program parameters, how to enter the system and change program
parameters, how to check the status of all system parameters and what occurs
during and after a power loss.
3-2 Applying Power
3-2.1 Power should only be applied when all wiring has been completed and
thoroughly checked for accuracy. The GDCP-A Control Panel polls its
transmitters at start-up. All transmitters should be connected and ready for
operation before applying power. Power to the transmitters is supplied by a
D.C. power supply located in the panel which connects to each transmitter
using three of the conductors in the connecting cable.
After making sure that the breaker at the facility’s service panel is in the on
position, place the power switch for the panel to the on position as noted on the
power supply/relay board located at the back of the panel P.C. package. You will
have to open the package door to access this switch. Please see Fig. 4, page
14, for the location of the panel’s power switch. The switch is located on
the top, left corner of the P.C. board to the right of the power input terminal
strip.
Immediately place the power switch to the off position if you experience
any indications of circuit shorting, unexpected noises or smoke. Do not
attempt to apply power until the reasons for these happenings are
determined and corrected.
3-2.2 Once the power switch is in the on position, close the door to the P.C. package.
Briefly examine the front panel for the following:
The display should have a message indicating the date and time. There
should also be a statement indicating that the unit is warming up and
asking the operator to please wait.
The green power indicator at the upper, right corner of the front panel
should be glowing.
All other panel indicators should be in their off positions.
WARNING
Dangerous, high voltage exists on the panel’s power supply/relay board. Be especially
careful not to contact any of the terminal points on TS1 or the main power fuse, FH1,
while operating the power switch, SW1.
