Temperature Controller - Staveb AG

2-12 PreparationsAlarm Output 1/Control Output 2• On the Bulletin 900-TC32, Alarm Output 1 (ALM1) is across terminals5 and 6. When heating and cooling control is used, Alarm Output 1becomes control output 2.• When the Input Error Output parameter is configured to ON, alarmoutput 1 turns ON when an input error occurs.• The equivalent circuits for terminals 5 and 6 are shown for alarm output1 in the following diagram.Figure 2.105 6ALM1/Control OUT2/Input errorController alarm relay specifications are as follows:Table 2.CType Voltage Steady-State Resistive Current Electrical LifeSPST-NO 250V AC 3 A (max. resistive load) 100,000 operations30V DC 5 A (max. resistive load)1V 1 mA (min. resistive load)Communication (RS-485) to a Personal Computer (Requires 900BuilderSoftware)• When the Bulletin 900-TC32 controller is ordered with thecommunication option (see Table 1.A) communicating with a personalcomputer is possible.
