Installation & Maintenance Manual Digital Pressure Switch Series ZSE30/ISE30 Safety Instructions The Digital Pressure Switch and this manual contain essential information for the protection of users and others from possible injury and property damage and to ensure correct handling. Please check that you fully understand the definition of the following messages (signs) before going on to read the text, and always follow the instructions. IMPORTANT MESSAGES Read this manual and follow its instructions. Signal words such as WARNING and NOTE, will be followed by important safety information that must be carefully reviewed. Indicates a potentially hazardous situation which could result in death or serious injury if you do not follow instructions. Specification Safety Instructions (continue) • Insert a noise filter (line noise filter, ferrite element or other element) between the switching regulator and pressure switch when analog output is used. • Do not use with a corrosive or inflammable gas or liquid. • Do not press the setting buttons with a sharp pointed object. • Turn power on for 20 to 30 minutes before detecting fine pressure. Initial drift of about ±1% occurs immediately after turning the power on. • The direct-current power supply to combine should be a UL authorization class 2 power supply based on UL1310, or a power supply using a transformer which is class 2 based on UL1585. • Only a pressure switch with UL mark on the body is UL approved. • This pressure sensor is for use with air only. Please contact SMC if the switch is to be used with other fluids.

Otherwise, malfunction may potentially result due to noise. • Be sure to ground Terminal FG when using a switching regulator obtained on the commercial market. If the analog output is connected to a switching regulator obtained on the market, switching noise will be superimposed and product specification can no longer be met. This can be prevented by inserting a noise filter, such as a line noise filter and a ferrite element, between the switching regulator and the pressure switch, or by using a seriespower supply instead of a switching regulator. Connector Connecting/Disconnecting • When connecting the connector, insert it straight onto the pins and lock the connector into the square groove in the housing unit connector clicks. • When disconnecting the connector, press the connector lever to disengage the lever claw from the square groove. Then pull the connector straight out.

Press the or button to enter the Set Value Change mode. The first digit will flash. 2. Press the or button to set the desired value. (No operation within ten seconds after the Set Value Change mode was selected results in automatic setting of the value appearing in the display window and in charging of the mode to Set Value Change mode to Set Value Indication mode.) 3. Press the button to make the next digit flash. (If the highest digit is zero, “ ” or “ ” will flash. “ ” means “+zero”, “ ” means “-zero”.) (When the button is pressed at the third digit, the first digit will flash). 4. Press the button continuously for longer than one second to return to displaying set values. Other Functions ZISE##-TFI48GB-A Peak and Bottom Hold Display Function Maximum and minimum values are always detected and updated during measurement. Displayed values can be held. For peak hold, Press and hold the button for longer than one second to hold the maximum pressure value. The display will flash. To reset holding, press and hold the button for more than one second. The display will return to measurement mode. For buttom hold, press and hold the button for longer than one second to hold the minimum pressure value. To display will flash To reset holding, pressure and hold the button for more than one second. The display will return to measurement mode. Key Lock Function This function prevents malfunction such as a set value being changed by mistake. Press and hold the button for longer than four seconds to display which of “Loc” or “UnL” is currently set. Select by pressing the or button and set by presing the button. If button operation is not desired, set to “Loc” to set the Lock mode. To release key lock, Press and hold the button for longer than four seconds to display the current setting and set to “UnL”. Zero Clear Function The displayed value can be adjusted to zero when pressure to be measured is within ±70digits of the atmospheric pressure. (The range of ±10% F.S.setting is different depending on the individual product difference) This function is useful because it enables the detection of pressure fluctuations larger than a certain value without being influenced by fluctuations of source pressure. Press continuously the and buttons simultaneously to reset to “0” on the display. and return to the Measurement mode automatically. Error Display Function This function displays error location and nature when a problem or an error occurs. Error Name Error Display Overcurrent Error Residual Pressure Error Pressurizing Error Error Nature Troubleshooting Method A load current is flowig to the switch output of 80mA or more. Turn the power off and remove the cause of the output oovercurrent. Then turn the power on. Pressure more than ±0.071MPa for 1MPa or more than ±7.1kPa for vacuum compared with the atmospheric pressure is applied during zero clear operation. In three seconds, the mode will reset to the Measurement mode. ±10% F.S. of the setting range changes with individual product differences. Perform zero-clear operation again after restoring the applied pressure to an atmospheric pressure condition. Pressure outside of the high limit of the set pressure range is applied. Pressure outside of the low limit of the set pressure range is applied. Reset applied pressure to a level within the set pressure range. Displayed in the case of an internal data error. System Error Displayed in the case of an internal data error. Displayed in the case of an internal data error. Displayed in the case of an internal data error. Turn the power off and turn it on again. If resetting fails, an investigation by SMC Corporation will be required. Contact AUSTRIA BELGIUM CZECH REP.
