6. RELAY OUTPUTS 6.1 OUTPUT SETUP AND SPECS 1. 3 relay outputs. SPST relay contacts going to spade terminals #4-9. 2. The outputs are rated at 3A, or 8A resistive load. 3. Each output (1-3) can be controlled via Modbus RTU Communication by setting on or off to the 1on, 2on, 3on parameters. 4. Each output can be configured to operate as a control output, typically for temperature control. This is done when 1on, 2on, 3on respectively are set to rEG. This is the default setting. a.
6.3 OUTPUT 2 2ND STAGE (oS2=Std 2on=rEG) Kind of action: Heating Reference probe: TP1 Terminals: SPADE 6 & 7 Related Parameters: S2c, St2, Hy2, LS2, US2, AC2, oS2, 2on Probe1 Set2 Set2+ Hy2 time Out2 time NOTES 1. Output 2 will function as an output temperature control when oS2=Std, otherwise output 2 is an alarm output contact. 2. S2c determines if St2 is relative to St1 or independent. (S2c=dep or ind). 3. Hy2 functionality same as Hy1. See OUTPUT 1 CALL FOR HEAT. 6.
6.5 OUTPUT 3 TEMPERATURE PROTECTION (3on=rEG) Kind of action: Heating Reference probe: TP1 or TP2 Terminals: SPADE 8 & 9 Related Parameters: S3c, St3, Hy3, LS3, uS3, AC3, 3on, o3P Probe2 Set3 Set3+ Hy3 time Out3 time NOTES 1. Output 3 can be used to enable pumps when temperature falls below a St3. 2. o3P will select the probe for Output 3. Pb1 or Pb2.
6.6 OUTPUT 3 ALTERNATE SET POINT Kind of action: Heating Reference probe: TP1 or TP2 Related Parameters: St3, Hy3, LS3, US3, AC3, St5, Hy5, 3on, o3P, SSE, AC5, ACA NOTES 1. When SSE is enabled and Output 1 is in a de-energized state (off) Output 3 will function according to St3. When Output 1 is in an energized state Output 3 will function according to St5. 2. ACA delays the change from St3 to St5. 3. o3P selects temperature probe to be referenced by Output 3. 4.
7. MODULATION OUTPUT Kind of action: if Sr< 0 Heating; if Sr>0 Cooling. See diagrams. Current (mA) 20 Current (mA) 20 Sr < 0 4 Sr > 0 4 Set4 + Sr Set4 Temper. Set4 Set4 + Sr Temper. Reference probe: TP1 Related Parameters: S4c, St4, Sr, PS4, PP4, Ac4, i1S, i1t, i1F, i1d NOTES 1. The kind of action of the modulation output depends on the sign of the Sr parameter. 2.
8. MODULATION BUFFER Probe 2 Th4 Th4+HY4 20ma Out 4 Time 4ma Kind of action: Heating Reference probe: TP2 Related Parameters: Th4, HY4 NOTES 1. This function references probe TP2 and will trigger output 4 to reduce the signal to 4mA when the temperature of Th4 is reached by TP2 and hold it until TP2 drops below TH4+HY4. Output 4 then returns to normal operation referencing TP1. 9.
11. HOT KEY PROGRAMMING To upload program from control to HOT KEY: Insert HOT KEY into the TTL/HOT KEY connection on the back of the control. Press + and keys together momentarily then press the key. The uPL message will appear while uploading is occurring and the End message will appear when finished. Push any key to return to normal operation. To download program from HOT KEY to control: ON/OFF Press the ON/OFF key to turn off the control.
12. ASSIGNING TEMPTRAC® ADDRESS FOR MODBUS RTU The first step to interfacing a BAS (Building Automation Control) with a boiler or group of boilers will be the assignment of the address number for each boiler. 1. Enter the Programming mode by pressing the Set (lead with the SET key.) and DOWN key for 3s. 2. Press the DOWN key. 3. Select “Pr2” – “PAS” parameter and press the “SET” key. 4. The value “0 - -” with a flashing zero is displayed. 5.
13. ALARMS Alarm messages are displayed in the lower display of the TempTrac and are alternated with the default message. These alarm messages are displayed together with the icon devoted to signalling the alarm conditions. Message Cause “P1” “P2” “P3” “HA” “LA” “AL1” “AL2” “AL3” “Nn1” “Nn2” “Nn3” “rtc” “rtF” Page 22/ 24 Outputs and information Audible alarm sounds. Output 1 and 2, if depending on the probe, open; TP1 probe failure.
13.1 DIGITAL INPUT ALARMS Digital Inputs Polarity of the inputs is determined by the i1p, i2p, i3p parameters. If they are set to “CL” (closed) then a signal is present when the input terminal has a connection to the common (COM) terminal #21. When the parameter is set to “OP” (open) then a signal is present when the input terminal does not have a connection to the common (COM) terminal. Digital Input 1 (Screw terminal #18, COM #21) 1.
13.3 ALARM RECOVERY 1. Probe alarms: “P1”, “P2”, and “P3”; automatically stop a few seconds after the probe returns to normal operation. Check connections before replacing the probe. 2. Temperature alarms “HA” and “LA” automatically stop as soon as probe 1 temperature returns to AFH degrees below or above the alarm value respectively. 3. The digital input 1 alarm recovers automatically when the need for output 1 stops.
