• A Certified AC power (mains) disconnect or circuit breaker should be mounted near the SafeGuard Controller and installed following applicable local and national codes. If a switch is used instead of a circuit breaker, a properly rate CERTIFIED fuse or current limiter is required to installed as per local or national codes. -
Page 5: General Description
System configuration is through user friendly menus and all configuration data is retained in non-volatile memory during power interruptions. The SafeGuard Controller’s front panel is shown below in Figure 1.0 displaying the 8 channel bar graph screen. Additional data screens are shown in Figure 2.0. -
Page 6: Data Display Screens
1.1.1 TREND SCREEN The SafeGuard Controller’s Trend screen shown in Figure 2.0 displays a 24 hour trend of input data for the channel selected. Horizontal tic marks are each hour and vertical tic marks are each 10% of full scale. Dashed lines indicate alarm levels. The graphic LCD is 240 pixels wide so each pixel represents 1/10 hour, or 6 minutes worth of data. -

SafeGuard Controller may be set for 8 channel mode, deactivating channels 9-16. This is done in the System Setup menu described in section 2.3. The SafeGuard Controller will only allow 15 channels to be turned off. At least one channel must remain on. -
Page 17: Cal Mode
2.2.7 CAL MODE This SafeGuard Controller feature is only accessible when Sensor Direct or Analog Input with Local Cal. is selected. The Analog Input with Local Cal. option may be used if the transmitter and sensor connected to the controller are located in an area not easily accessible. -

ID settings are per channel as described in section 2.2.4). This slave port may be used to transfer the SafeGuard Controller data to a host device such as a PC, PLC, DCS or even another SafeGuard Controller. The slave port is addressable, allowing many SafeGuard Controllers to be connected to a single RS-485 cable. -
Page 22: Eight / Sixteen Channel Modes
If 8 channels are selected by this menu they are channels 1-8 and 9-16 are disabled. One way the SafeGuard Controller cost is kept low is Input / Output option PCB’s are arranged into groups of 8 channels. Therefore, users with less than 9 channels require only 1 PCB and do not pay for I/O hardware for 16 channels. -
