Push-button operations
Use both push-buttons simultaneously to:- make a complete relay reset, i.e. clear memorized values
and release latched output relays- store a new setting value- test an output relay
Use the PROGRAM push-button to:- enter a submenu from the main menu- enter the setting mode of an adjustable parameter- control the cursor in the setting mode or- control the selected output in the test mode
Use the RESET/STEP push-button to:- reset operation indicators- step forward or backward in main menus or submenus - scroll set values in the setting mode

Motor Protection Relay SPAM 150 CThermal unit equationsHeating during overload:�A = (l / (1.05 x l�))2 x (1-e -t/�) x 100%�B = (l / (1.05 x l�))2 x (1-e-t/�) x p%
Cooling at normal load or during standstill:When the current falls below 1.0 x l��, the thermal curve A is linearly brought down to the level of the thermal history curve B as shown in curve part C. This corresponds to the levelling out of the hot spots in the motor. Thereafter the cooling follows the lower curve with a time constant equal to the heating time constant as long as the motor is running at normal load or idling.For a motor at standstill, i.e. when the current is below 12% of l��, the cooling can be expressed as:Q=Q02 x e -t/kc x �, where Q0 is the initial thermal level and kc is the cooling time multiplier.In the equations above, the heating time constant can be substituted by ��� 32 x t6x.The thermal unit is supervised twice a second in the relay, giving a maximum trip time resolution of 0.5 s.
