Under “Relay Override Status”, selecting “On” will open a pop-up window to force the relay into its active state – as if its setpoint was exceeded. -
Page 37: Setting Automatic Overrides
Setting Automatic Overrides Each relay can schedule up to four separate times for an automatic override. Of these times, three may be used to force the relay into an active state while one may be used to force it into an inactive state. -
Page 38: Configuring Bacnet
Should too many changes be made that cause the panel to operate in an undesirable manner, Two options are available to reset the GDCP-Touch under Settings > Reset Options. “Reset to Default” will erase any custom sensor, relay, or zone settings while leaving all assignments intact. -
Page 39: Using The Analog Outputs
21 on page 59 of this manual. As an example, a Brasch Carbon Monoxide Transmitter has a full scale output of 200 PPM CO. For the 4-20 mA output mode with a single sensor configured, 0 PPM CO would equal 4 mA while 200 PPM CO would equal 20 mA. -
Page 40: Obtaining The Best Operation
Obtaining the Best Operation Carbon Monoxide and/or Nitrogen Dioxide Transmitters This panel is designed to control the ventilation system in response to a rising concentration of the target gas at its transmitters. No two installations will be exactly the same. Different ventilation components, the number of gas producing sources, air flow patterns inside the room, the total room volume, and the exact location of the transmitters influence how effective the system is in controlling the target gas concentration. -
Page 41: Maintenance
Maintenance Testing the Response to the Target Gas Carbon Monoxide and/or Nitrogen Dioxide Transmitters Testing these transmitters requires that the target gas be applied to the sensor using one of two methods. Gas can be applied from a tank of air containing a known concentration of the target gas or from the exhaust of an operating engine to produce a level of target gas sufficient to elicit a response from the control panel. -
Page 42: Replacing The Sensor
However, sufficient response can be obtained to determine that the transmitter is working. Brasch Environmental Technologies recommends testing the transmitters once every six months to ensure proper response and accuracy. Replacing the Sensor The sensor’s useful lifetime depends greatly upon its operating conditions. -
Page 43: Suggested Repair Parts
This control panel contains few field serviceable parts. However, the battery and fuses are replaceable in the field. While an open fuse may indicate problems with the circuitry, fuses may also open because of power surges or ventilation component failure. Brasch recommends that the following parts be available for replacement. -
Page 44: Troubleshooting
Troubleshooting Error Messages The GDCP-Touch is programmed to display error messages to indicate a problem condition with the unit. The bottom center of the Home Screen will scroll through each message present. When an error occurs, the alarm will chirp and a silence button will replace the calendar icon to allow a user to mute the alarm. -
Page 45: Sensor # Sensor Missing
When this error message appears, replace the sensor board. Sensor # Sensor Missing If no gas sensor is present on the sensor board, this error message will appear on the display. Verify that there is a sensor on the sensor board and that it is fully seated in its socket. If not, place the sensor firmly into the socket. -
Page 46: Checking And Replacing The Battery
The real-time clock circuitry is powered by a single CR1220 lithium-ion battery. This circuit is responsible for maintaining the date and time settings while the GDCP-Touch does not have power. If the date and time settings reset after a power cycle, the CR1220 battery may need to be replaced. -
Page 47: Common Installation/Operation Mistakes
Improper communication wiring, or exceeding the number of nodes on a single bus, can cause communication between the panel and transmitters to be inconsistent. The GDCP-Touch uses Modbus RTU over RS-485 for communication. All standard guidelines apply for this type of wiring. -
Page 48: Delay Period Set Incorrectly
concentration to that which produces the most efficient ventilation system operation while protecting people in the monitored area. Setting the concentration too high can create a situation in which the target gas concentration becomes dangerous, or the area contains too much smoke from engine exhaust. -
Page 49: Relay Activation Type Set Incorrectly
Brasch strongly recommends that the control panel be grounded according to applicable wiring codes. However, if this is not possible, using a stylus or otherwise ensuring that the touch input is at the same potential as the floating ground will improve touch accuracy and responsiveness. -
