This module requires an industry-standard 11-pin socket. Order API 011 or finger-safe API 011 FS socket separately. Power Input Terminals – The white label on the side of the API module will indicate the power requirements. AC power is connected to terminals 1 and 3. For DC powered modules, polarity MUST be observed. Positive (+) is wired to terminal 1 and negative (–) is wired to terminal 3. Signal Input – Polarity must be observed when connecting the signal input. The positive connection (+) is applied to terminal 4 and the negative (–) is applied to terminal 5. Relay Output Terminals – Terminals 6, 7, 8 and 9, 10, 11 provide the appropriate connections for the desired relay operations. (NO = Normally Open, NC = Normally Closed, C = Common). WIRING EXAMPLES Powered 4-20 mA or Voltage Input Device SETUP The API 1080 G input selector switch determines the input impedance for the module, typically 50 Ω for current inputs and 250 kΩ or greater for voltage inputs. The switch settings will determine the exact operation of the module. Following are the standard input range and alarm configuration tables used to configure the API 1080 G. Set switches A, B, C and D accordingly. 28 Contact Set 1 Passive 2-Wire Input Device (+) (–) NO C NC (+) (–) No connection Contact Set 1 NO C NC (–) 4 5 6 7 8 Socket top view API 1080 G with Powered Current or Voltage Input (+) 3 2 1 11 10 9 4 5 3 2 1 6 11 7 8 Socket top view 10 9 +18 VDC Loop Power, Unregulated API 1080 G Using +18V Loop Power Supply AC or DC (–) Power Input AC or DC (+) NC C NO AC or DC (–) Power Input AC or DC (+) NC C NO Contact Set 2 Contact Set 2 VOLTAGE Inputs CURRENT Inputs Set switch A to “V” Set switch A to “I” ALARM CONFIGURATION Range Switches Range Switches Type Latch Action Switch B C B C D 0-50 mV 8 1 0-1 mA C 1 HI No Normal 2 0-100 mV 9 1 0-2 mA 0 1 HI No Reverse 6 0-200 mV A 1 0-4 mA 1 1 HI Yes Normal 0 0-250 mV C 1 0-8 mA 2 1 HI Yes Reverse 4 0-400 mV B 1 2-10 mA 2 F LO No Normal 3 0-500 mV 0 1 0-10 mA 4 1 LO No Reverse 7 0-1 V 1 1 0-16 mA 3 1 LO Yes Normal 1 0-2 V 2 1 0-20 mA 5 1 LO Yes Reverse 5 0-2.5 V 4 1 4-20 mA 5 F 0-4 V 3 1 1-5 V 5 F 0-5 V 5 1 0-10 V 6 1 ±5 V 6 4 ±10 V 7 4 API maintains a constant effort to upgrade and improve its products. Specifications are subject to change without notice. Consult factory for your specific requirements. SETUP (Continued) EXAMPLE: For 4-20 mADC input, HI alarm, non-latching, normal action set switches as follows: A = I (current) B = 5 C = F D = 2 Setpoint Control – This multiturn potentiometer allows the operator to adjust the level at which the alarm is activated. This control is adjustable from 0 to 100% of the input range. Deadband Control – This potentiometer allows the alarm trip and reset window to be adjusted symmetrically about the setpoint from 1 to 100% of the span. This allows the operator to fine tune the point at which the alarm trips and resets. The deadband is typically used to prevent chattering of the relays or false trips when the process signal is unstable or changes rapidly. Test Switch – The functional Test pushbutton toggles the alarm status independent of the input when depressed. It verifies the alarm and system operation without having to alter the input signal. OPERATION GREEN LoopTracker ® Input LED – Provides a visual indication that a signal is being sensed by the input circuitry of the module. It indicates the input signal strength by changing in intensity as the process changes from minimum to maximum. If the LED fails to illuminate, or fails to change in intensity as the process changes, this may indicate a problem with module power or signal input wiring. Bi-Color Alarm LED – Provides a visual indication of the alarm status. In all configurations, a GREEN LED indicates a non-alarm condition and a RED LED indicates an alarm condition. Alarm Relays – In the normal mode of operation (failsafe), the relay coil is energized in a non-alarm condition and de-energized in an alarm condition. This will create an alarm condition if the module loses power. For a normal acting, nonlatching configuration, the alarm will activate when the input signal exceeds the setpoint (HI alarm) or falls below the setpoint (LO alarm), then will automatically reset when the alarm condition no longer exists. For a reverse acting alarm (non-failsafe), the relay coil is de-energized in a nonalarm condition and energized in an alarm condition. The alarm activates when the input signal exceeds the setpoint (HI alarm) or falls below the setpoint (LO alarm), then automatically resets when the alarm condition no longer exists. When the latching mode is selected, it will be necessary to push the functional test pushbutton or remove power from the module to reset the alarm. The alarm will only reset if the alarm condition no longer exists. CALIBRATION The module input ranges are factory calibrated and no calibration is required. To calibrate the alarm section, set the deadband control to the minimum. Set the signal source to a reference that represents the desired trip point. Adjust the setpoint control to the point at which the relay changes state form a non-alarm to an alarm condition. The deadband will be 1.0% of span in this case. Turn the deadband potentiometer clockwise if a larger amount of deadband is desired. The deadband is symmetrical about the setpoint; both transition points will change as deadband is increased. The test button can be used at any time to toggle the relay state independent of the input and output to verify operation.
